Synonyms in Solr Query Results

Whenever I query a string in solr, i want to get the synonyms of field value if there exists any as a part of query result, is it possible to do that in solr

Solution

  • There is no direct way to fetch the synonyms used in the search results. You can get close by looking at how Solr parsed your query via the debugQuery=true parameter and looking at the parsedQuery value in the response but it would not be straightforward. For example, if you search for "tv" on a text field that uses synonyms you will get something like this:

    $ curl "localhost:8983/solr/your-core/select?q=tv&debugQuery=true"
{
...
    "parsedquery":"SynonymQuery(Synonym(_text_:television _text_:televisions _text_:tv _text_:tvs))",
...

    Another approach would be to load in your application the synonyms.txt file that Solr uses and do the mapping yourself. Again, not straightforward,
