Hello, I'm trying to find a solution for multiwords synonyms in solr 9.2.1.
We cannot use sow=false because our different fields have different stopwords and synonyms, ie they are not consistently analyzed and we dont want SolR to use a field centric query ((as explained here: https://opensourceconnections.com/blog/2018/02/20/edismax-and-multiterm-synonyms-oddities/ ). I'm trying the solution described here ( https://opensourceconnections.com/blog/2016/12/02/solr-elasticsearch-synonyms-better-patterns-keyphrases/) but in SolR instead of ES, so I have a field define as <fieldType name="multiwords_synonyms" class="solr.TextField" positionIncrementGap="100"> <analyzer type="index"> <tokenizer name="standard" /> <charFilter class="solr.MappingCharFilterFactory" mapping="mapping-ISOLatin1Accent.txt" /> <filter name="lowercase"/> </analyzer> <analyzer type="query"> <tokenizer name="standard" /> <charFilter class="solr.MappingCharFilterFactory" mapping="mapping-ISOLatin1Accent.txt" /> <filter name="lowercase" /> <filter class="solr.ShingleFilterFactory" maxShingleSize="3" minShingleSize="3" outputUnigrams="false"/> <filter class="solr.SynonymGraphFilterFactory" synonyms="multiwords_synonyms.txt" ignoreCase="true" expand="true"/> <filter name="flattenGraph"/> <filter class="solr.KeepWordFilterFactory" words="has_multiwords_synonym.txt" /> </analyzer> </fieldType> Where multiwords_synonyms.txt contains the line hotel\ de\ ville=>mairie but it doesnt work on the query side, with the query "hôtel de ville paris" I have the shingle "hotel de ville" but the synonym hotel\ de\ ville=>mairie doesnt match with the ShingleFilterFactory output. If someone has a clue it would be greatly appreciated. Best regards, Elisabeth
