Would it work to index the upper-case LET as something else? For instance, index it as '$let'
Now, all your searches are on one index, but you have to substitute '$let' where you want to find LET in your query.. This won't match your other occurrences of let... You'll have to watch to be sure your displays are appropriate. That is, depending upon how you store your data for display you'd have to translate '$let' back into 'LET'...... This should also work for span queries, etc..... This won't foul you up if you use wildcards as long as you don't allow the wildcards to appear in the first character position...

I've run into a case where we want to search for the acronym 'LET', however this three letter word occurs very frequently in quite a number of documents. What I'm looking to do is a query that's case insensitive _except_ for that specific term. And, it appears to do so, things get very ugly, very quickly. According to http://www.gossamer-threads.com/lists/lucene/java-user/28131?page=last (I'm doing my homework first), it appears that one must keep a case-sensitive and case-insensitive version in the index, if not two separate indexes. While this makes sense up to a point, allowing me to search one field or the other; I'm looking for distances between words, it seems things get far more complicated. Because, should I store both versions and happen to know that the tokens are the same and that their positions are identical, is there a way do things like: "LET organization" (where LET is case sensitive, but part of the phrase) "company LET"~10 (again, where LET is case sensitive, near the term company which is case insensitive) Would love to get some thoughts on how to go about approaching this.
