...As Erik points out in that thread, when dealing with a dictionary of "singleword" => ["multi" "word"], and ["multi" "word"] => "singleword" synonyms a very good/simple approach is to use an analyzer that allways normalizes down to the single word version (as a single token)
This allows you to leave the position incriment alone, and get Span/Phrase queries to work just fine.
But be aware of the drawbacks from replacing multiple words with its corresponding acryonym/alias during analysis. The analyzis at search-time cannot perform the normalization to a single word if the rest of the words in the search string are not recognized:
- Prefix search: [cyber] [ca*] would not match [cybercafe] - Wildcard search: [cyber] [ca?e] would not match [cybercafe] - Fuzzy search: [cyber] [cage~] would not match [cybercafe]
I am not sure that this is correct but perhaps someone in this forum can.
