Lucene search and underscores

Question

When I use Luke to search my Lucene index using a standard analyzer, I can see the field I am searchng for contains values of the form MY_VALUE. When I search for field:\"MY

Answer 1

I don't think you'll be able to use the standard analyser for this use case.

Judging what I think your requirements are, the keyword analyser should work fine for little effort (the whole field becomes a single term).

I think some of the confusion arises when looking at the field with luke. The stored value is not what's used by queries, what you need are the terms. I suspect that when you look at the terms stored for your field, they'll be "my" and "value".

Hope this helps,

Answer 2

It doesn't look like you used the StandardAnalyzer to index that field. In Luke you'll need to select the analyzer that you used to index that field in order to match MY_VALUE correctly.

Incidentally, you might be able to match MY_VALUE by using the KeywordAnalyzer.
