Search API Entity Translation Solr search

An extension module to 2.x version of Search API Entity Translation module.

An extension module to 2.x version of Search API Entity Translation module.

Changes the way in which Solr Search module stores the multilingual content, making it use solr dynamic fields for translatable entity fields.

For example, when indexing body:value field, solr would normally store its value in tm_body:value property. With this hook (assuming that body field is translatable and comes from translatable entity, and that currently being processed content language is fr) it will be stored in tm_fr_body:value instead, with nothing saved to default tm_body:value property.

This allows to use different datatypes for different language-based solr fields, thus allowing to configure different tokenizers/stemmers/spell checkers/stop words/protected words/etc for each language separately.

Obviously it also works when retrieving data from solr, looking for language-based dynamic fields, and, if they exist - assigning their values back to relevant Search API properties (not language-based anymore).

Additionally it modifies solr search queries run on multilingual indexes to add all possible multilingual field variants (or, if query runs on specific languages only, add field variants for those languages only) for all translatable fields being searched (which means that when tm_title_field is being searched on site with en and fr languages enabled, the search query will automatically include also tm_en_title_field and tm_fr_title_field fields in its qf parameter).

Finally, it auto-generates content for schema_extra_types.xml and schema_extra_fields.xml solr configuration files if needed. This can be found as 2 new vertical tabs within Search API server section on the Files tab.
