Hi Ian,
many thanks for the hints...based on your and Ericks hints i have taken
a deeper look into that...and the StandardAnalyzer which I'm using will
removed informations like "." and "-" from my queries
(+filename:testEXCEL-formats.xls) ...
In addition to Erick's advice, since you are storing filename without
analysis you could use a TermQuery to find it.
Does this mean i don't need to index the filename ?
> You can use
BooleanQuery to combine that with other queries, including those
generated by QueryParser.
Based on those advices i have made an implementation which modifies my
CustomerQueryParser:
protected Query getFieldQuery(String field, String term) throws
ParseException {
LOGGER.debug("getFieldQuery(): field:" + field + " Term: " + term)
if (FieldNames.REVISION.getValue().equals(field)) {
int revision = Integer.parseInt(term);
term = NumberUtils.pad(revision);
}
if (FieldNames.FILENAME.getValue().equals(field)) {
Term t = new Term(FieldNames.FILENAME.getValue(), term.toLowerCase());
TermQuery tq = new TermQuery (t);
BooleanQuery bq = new BooleanQuery ();
bq.add(tq, Occur.MUST);
return bq;
}
return super.getFieldQuery(field, term);
}
Based on my Unit Tests it works as expected...
But I'm not sure to understand the things like "queryparts
-filename:*.xls" correct..
Doesn't that mean that my implementation will change the behaviour into
the following:
"queryparts +filename:*.xls" or did i misunderstand things here ?
Thanks for your help...
Kind regards
Karl Heinz Marbaise
