My dictionary filter currently implements next() and everything works well
when dictionary entries are replaced one-to-one. For example: Can =>
Canada.
A problem arises when I try to replace it with more than one word. Going
through next() I encounter "shutdown". But the dictionary entry takes
Shutdown => shut down (two words). I construct a replacement term according
the to the instructions in the Javadoc, but the search does not match any
substrings "shut" or "down" in my database. I debugged it and found
QueryParser is converting my replaced text into PhraseQuery objects instead
of BooleanQuery objects.
My code to replace the string is below:
Token teachToken = new Token();
teachToken.resizeTermBuffer(replacementTerm.length());
char [] termBuffer = teachToken.termBuffer();
for (int i = 0; i < replacementTerm.length(); i++) {
termBuffer[i] = replacementTerm.charAt(i);
}
teachToken.setTermLength(replacementTerm.length());
this.tokenQueue.push(teachToken);
return teachToken;
Instead of [field1]:shut down, it is searching with [field1]:"shut down".
How can I construct the replacement terms so that queries are formed
properly, and I don't violate the next() contract?
use a private stack. When you replace a word, fill it, and the next()
will pop your stack. When the stack is empty, feed it again. So first
time next() will get "shut", and second time "down".
