I am having difficulty using MoreLikeThisQuery with an n-gram analyzer as its
analyzer.
A test query isn't hitting any document in a unit test case.
Is there any debugging method to use to understand why there is not hit?
Because the test code uses a RAMDirectory, I cannot use Luke to see if the index
was made correctly.
This is a snippet of the query code:
MoreLikeThisQuery mltQuery = new MoreLikeThisQuery(queryText, new String[]
{"source"}, //TODO: Make this array constant defaultFuzzyAnalyzer, "source"); //
defaultFuzzyAnalyzer is a 4-gram analyzer based on NGramTokenFilter.
mltQuery.setMinTermFrequency(1); mltQuery.setMinDocFreq(1);
mltQuery.setPercentTermsToMatch(threshold);mltQuery.setMaxQueryTerms(Integer.MAX_VALUE);
TopDocs topDocs = indexSearcher.search(mltQuery, max);
Thanks.
TK
