Subject Using a Lucene index dictionary
Date Thu, 28 Feb 2019 18:46:42 GMT
Hello cTakers!

I've been playing with the provided sample dictionaries that use
Lucene indexes generated by the CreateLuceneIndexForExampleDrugs.java
and CreateLuceneIndexForSnomedLikeSample.java scripts.

I think I have everything configured right from the output of the log:

<<<<<<<<<

That run was configured for the drug index exclusively and it seems to
say that the indexes were successfully loaded and the
DictionaryLookupAnnotator is happy. No error or warning in the log.

However, I get absolutely no results even if I use the keywords that
are mentioned in the script. (e.g. Acetaminophen, Aspirin, Ibuprofen,
Celexa). Not a single textsem or refsem tag. No mention of any of the
associated codes in the output; only the usual syntactic elements. The
terms are tagged as nouns as expected. The DictionaryLookupAnnotator
is invoked.

Same story if I switch to the SNOMED index. None of the twelve keywords trigger.

What am I missing and what do I need to do to get those dictionaries
to behave? Does anyone have a functional Lucene index?

Thanks,

          Remy Sanouillet
