lets say i do this while indexing:
doc.add(Field.Text("categoryNames", categoryNames));
Now while searching categoryNames, I do a search for "digital cameras".
I only want to match the exact phrase digital cameras with documents who
have exactly the phrase "digital cameras" in the categoryNames field. I
do not want results that have "digital camera batteries" part of the
result.
Whats the best way to accomplish this?
Hi Mufaddal,
One way to do this is to use the KeywordAnalyzer (in the Lucene
Subversion trunk, but not in v1.4.3; will be in forthcoming v1.9) for
the "categoryNames" field. This analyzer does not tokenize field
contents, so "digital cameras" would be a single token, and the only
thing that would match it would be the exact same single token. Be
careful when you search to construct the search tokens similarly.
If you have other fields you want to search, and you want to tokenize
their contents when you index them, you could use the
PerFieldAnalyzerWrapper, so that the KeywordAnalyzer is only used for
the "categoryNames" field.
