How should I handle cross-chunk matching with taxonomies?

I am trying to use a taxonomy with some long terms in it, such as fungal lung infectious disease. The chunker used by parsetree() puts fungal lung and infectious disease into separate chunks preventing the full term in the taxonomy from matching the text. One work around I can imagine would be to chunk the longer taxonomy terms into multiple taxonomies, but then I would need to use queries like like 'search("DISEASE_BEGINNING DISEASE_INSIDE*", text)'. Is there a better way to handle this?

Start by examining parsetree() and the taxonomy matching behavior described in the issue, then review how search() handles chunk boundaries. The issue does not name files or tests, and it does not define a specific implementation or acceptance criteria; clarification is needed before work can be considered done.
