Solr schema configuration and management.

Extend SolrSchema for your project and configure the fields, field types, and copy fields you want defined in Solr. Fields should be defined using SolrField and field types with SolrAnalyzer and SolrFieldType. For example:

from parasolr import schema

class MySolrSchema(schema.SolrSchema):
    '''Project Solr schema configuration'''

    # field declarations
    author = schema.SolrField('text_en')
    author_exact = schema.SolrStringField()
    title = schema.SolrField('text_en')
    title_nostem = schema.SolrStringField()
    subtitle = schema.SolrField('text_en')
    collections = schema.SolrField('text_en', multivalued=True)

    #: copy fields, for facets and variant search options
    copy_fields = {
        'author': 'author_exact',
        'collections': 'collections_s',
        'title': ['title_nostem', 'title_s'],
        'subtitle': 'subtitle_s',

Copy fields should be a dictionary of source and destination fields; both single value and list are supported for destination.

If you want to define a custom field type, you can define an analyzer for use in one or more field type declarations:

class UnicodeTextAnalyzer(schema.SolrAnalyzer):
    '''Solr text field analyzer with unicode folding. Includes all standard
    text field analyzers (stopword filters, lower case, possessive, keyword
    marker, porter stemming) and adds ICU folding filter factory.
    tokenizer = 'solr.StandardTokenizerFactory'
    filters = [
        {"class": "solr.StopFilterFactory", "ignoreCase": True,
         "words": "lang/stopwords_en.txt"},
        {"class": "solr.LowerCaseFilterFactory"},
        {"class": "solr.EnglishPossessiveFilterFactory"},
        {"class": "solr.KeywordMarkerFilterFactory"},
        {"class": "solr.PorterStemFilterFactory"},
        {"class": "solr.ICUFoldingFilterFactory"},

class SolrTextField(schema.SolrTypedField):
    field_type = 'text_en'

class MySolrSchema(schema.SolrSchema):
    '''Schema configuration with custom field types'''

    text_en = schema.SolrFieldType('solr.TextField',

    content = SolrTextField()

To update your configured solr core with your schema, run:

python solr_schema

This will automatically find your SolrSchema subclass and apply changes. See solr_schema manage command documentation for more details.

Model-based indexing with Solr.

Items to be indexed in Solr should extend Indexable. The default implementation should work for most Django models; at a minimum you should extend Indexable.index_data() to include the information to be indexed in Solr. You may also customize Indexable.index_item_type() and Indexable.index_item_id().

To manually index content in Solr, see index manage command documentation.

class parasolr.indexing.Indexable[source]

Mixin for objects that are indexed in Solr. Subclasses must implement index_id and index methods.


id separator for auto-generated index ids

classmethod all_indexables()[source]

Find all Indexable subclasses for indexing. Ignore abstract Indexable subclasses such as ModelIndexable.


Index the current object in Solr. Allows passing in parameter, e.g. to set a commitWithin value.

index_chunk_size = 150

number of items to index at once when indexing a large number of items


Dictionary of data to index in Solr for this item. Default implementation adds index_id() and index_item_type()


Solr identifier. By default, combines index item_type() and id with :attr:ID_SEPARATOR`.

classmethod index_item_type()[source]

Label for this kind of indexable item. Must be unique across all Indexable items in an application. By default, uses Django model verbose name. Used in default index id and in index manage command.

classmethod index_items(items, progbar=None)[source]

Indexable class method to index multiple items at once. Takes a list, queryset, or generator of Indexable items or dictionaries. Items are indexed in chunks, based on Indexable.index_chunk_size.

  • items – list, queryset, or generator of indexable objects or dictionaries
  • progbar – optional progressbar.Progressbar object to
  • when indexing items in chunks. (update) –

Total number of items indexed

classmethod items_to_index()[source]

Get all items to be indexed for a single class of Indexable content. Subclasses can override this method to return a custom iterable, e.g. a Django QuerySet that takes advantage of prefetching. By default, returns all Django objects for a model. Raises NotImplementedError if that fails.


Remove the current object from Solr by identifier using index_id()

solr = None

solr connection


recursive method to find all subclasses


Object-oriented approach to Solr searching and filtering modeled on django.models.queryset.QuerySet. Supports iteration, slicing, counting, and boolean check to see if a search has results.

Filter, search and sort methods return a new queryset, and can be chained. For example:

SolrQuerySet(solrclient).filter(item_type='person')                             .search(name='hem*')                             .order_by('sort_name')

If you are working with Django you should use parasolr.django.SolrQuerySet, which will automatically initialize a new parasolr.django.SolrClient if one is not passed in.

class parasolr.query.queryset.EmptySolrQuerySet(*args, **kwargs)[source]

Marker class that can be used to check if a given queryset is empty via isinstance():

assert isinstance(SolrQuerySet().none(), EmptySolrQuerySet) -> True
assert isinstance(queryset, EmptySolrQuerySet) # True if empty
class parasolr.query.queryset.SolrQuerySet(solr)[source]

A Solr queryset object that allows for object oriented searching and filtering of Solr results. Allows search results to be pagination using slicing, count, and iteration.

qs = qs.facet('item_type')

would result in item_type being the only facet field.

Return type:SolrQuerySet
facet_field(field, exclude='', **kwargs)[source]

Request faceting for a single field. Returns a new SolrQuerySet with Solr faceting enabled and the field added to the list of facet fields. Any keyword arguments will be set as field-specific facet configurations.

Return type:SolrQuerySet
facet_range(field, **kwargs)[source]

Request range faceting for a single field. Returns a new SolrQuerySet with Solr range faceting enabled and the field added to the list of facet fields. Keyword arguments such as start, end, and gap will be set as field-specific facet configurations.

Return type:SolrQuerySet
filter(*args, tag='', **kwargs)[source]

Return a new SolrQuerySet with Solr filter queries added. Multiple filters can be combined either in a single method call, or they can be chained for the same effect. For example:

queryset.filter(item_type='person', birth_year=1900)

A tag may be specified for the filter to be used with facet.field exclusions:

queryset.filter(item_type='person', tag='person')

To provide a filter that should be used unmodified, provide the exact string of your filter query:

queryset.filter('birth_year:[1800 TO *]')

You can also search for pre-defined using lookups on a field, for example:

queryset.filter(item_type__in=['person', 'book'])

Currently supported field lookups:

  • in : takes a list of values; supports ‘’ or None to match on field not set
  • exists: boolean filter to look for any value / no value
  • range: range query. Takes a list or tuple of two values
    for the start and end of the range. Either value can be unset for an open-ended range (e.g. year__range=(1800, None))

queryset.only('title', 'author', 'date')
queryset.only('title:title_t', 'date:pubyear_i')
Return type:SolrQuerySet

Apply sort options to the queryset by field name. If the field name starts with -, sort is descending; otherwise ascending.

Return type:SolrQuerySet

Return a new SolrQuerySet with the results populated from Solr. Any options passed in via keyword arguments take precedence over query options on the queryset.

Return type:SolrQuerySet

Construct query options based on current queryset configuration. Includes filter queries, start and rows, sort, and search query.

Return type:Dict[str, str]

Add abritrary raw parameters to be included in the query request, e.g. for variables referenced in join or field queries. Analogous to the input of the same name in the Solr web interface.

Return type:SolrQuerySet

This module provides indexing support for Django models. Also see Indexable.

To use, add ModelIndexable as a mixin to the model class you want to be indexed. At minimum, you’ll want to extend the index_data method to include the data you want in the indexed:

def index_data(self):
    index_data = super().index_data()

    # if there are some records that should not be included
    # return id only. This will blank out any previously indexed
    # values, and item will not be findable by type.
    # if not ...
        # del index_data['item_type']
        # return index_data

    # add values to index data
    return index_data

You can optionally extend items_to_index() and index_item_type().

class parasolr.django.indexing.ModelIndexable[source]

Find a related model for use in signal-based indexing. Supports app.Model notation or attribute on the current model (supports queryset syntax for attributes on related models.)

classmethod identify_index_dependencies()[source]

Identify and set lists of index dependencies for the subclass of Indexable.


Provides SolrQuerySet subclasses that will automatically use SolrClient if no solr client is passed on.

class parasolr.django.queryset.AliasedSolrQuerySet(solr=None)[source]

Combination of SolrQuerySet and AliasedSolrQuerySet

class parasolr.django.queryset.SolrQuerySet(solr=None)[source]

SolrQuerySet subclass that will automatically use SolrClient if no solr client is passed on.

:param Optional parasolr.solr.client.SolrClient:


This module provides on-demand reindexing of Django models when they change, based on Django signals. To use this signal handler, import import it in the ready method of a django app. This will automatically bind connect any configured signal handlers:

from django.apps import AppConfig

class MyAppConfig(AppConfig):
    name = 'myapp'

    def ready(self):
        # import and connect signal handlers for Solr indexing
        from parasolr.django.signals import IndexableSignalHandler

To configure index dependencies, add a property on any ModelIndexable subclass with the dependencies and signals that should trigger reindexing. Example:

class MyModel(Model, ModelIndexable):

    index_depends_on = {
        'collections': {
            'post_save': signal_method,
            'pre_delete': signal_method

The keys of the dependency dict can be:

  • an attribute on the indexable model (i.e., the name of a many-to-many relationship); this will bind an additional signal handler on the m2m relationship change.
  • an attribute on a related model using django queryset notation (use this for a secondary many-to many relationship, e.g. collections__authors)
  • a string with the model name in app.ModelName notation, to find and load a model directly

The dictionaries for each related model or attribute should contain:

Currently attribute lookup only supports many-to-many and reverse many-to-many relationships.

Typically you will want to bind post_save and pre_delete for many-to-many relationships.

class parasolr.django.signals.IndexableSignalHandler[source]

Signal handler for indexing Django model-based indexables. Automatically identifies and binds handlers based on configured index dependencies on indexable objects..

static connect()[source]

bind indexing signal handlers to save and delete signals for Indexable subclassess and any indexing dependencies

static disconnect()[source]

static handle_save(sender, instance, **kwargs)[source]

reindex on save if an instance of ModelIndexable

Manage Commands

Solr schema

solr_schema is a custom manage command to update the configured schema definition for the configured Solr instance. Reports on the number of fields that are added or updated, and any that are out of date and were removed.

Example usage:

python solr_schema


index is a custom manage command to index content into Solr. It should only be run after your schema has been configured via solr_schema.

By default, indexes _all_ indexable content.

You can optionally index specific items by type or by index id. Default index types are generated based on model verbose names.

A progress bar will be displayed by default if there are more than 5 items to process. This can be suppressed via script options.

You may optionally request the index or part of the index to be cleared before indexing, for use when index data has changed sufficiently that previous versions need to be removed.

Example usage:

# index everything
python index
# index specific items
python index person:1 person:1 location:2
# index one kind of item only
python index -i person
# suppress progressbar
