Hey there,
so let me quickly explain what is going on here.
you search for: sql server (without quotes) which QueryParser will
turn into a BooleanQuery like sql OR server since the StandardAnalyzer
you are using splits on whitespaces. That query will return all
document either containing sql or server. So far so good. If you want
to do a phrase search you should put the terms into quotes like that:
String line = "\"sql server\"";
Next you are trying to get the term frequency for "sql server" as a
single term which does not exist in your index since you used
StandardAnalyzer during indexing which again splits your text on
white-spaces. This will likely return 0 all the time ey?
hope that helps
