Is there an existing TokenFilterFactory that can conditionally insert
synonyms based on a given document attribute, say category? Some
synonyms only make sense in context: "bats" in Sports is different from
"bats" in "Party and Novelty".
It seems the synonyms.txt file would need an additional column that
could be checked against the document attribute prior to appending synonyms:
*#synonyms category*
post,pole sports
wheel,caster furniture
pat,paddy,patrick holiday
Is anything like this possible without writing a custom TokenFilterFactory?
