"I can go with the "title" field and have that include the synonyms in analysis. Only problem is that the number of fields and number of synonyms files are quite a lot (~ 8 synonyms files) due to different weightage and type of expansion (exact vs partial) based on these. Hence going with this approach would mean creating more fields for all these synonyms (synonyms.txt)
So, I am looking to build a custom parser for which I could supply the file and the field and that would expand the synonyms and return a score. " Having a binary or scalar feature is completely up to you and the way you configure the Solr feature. If you have 8 (copy?)fields with same content but different expansion, that is still ok. You can have 8 features, one per type of expansion. LTR will take care of the weight to be assigned to those features.
