Analyzer analyzer = new StandardAnalyzer(new String[]{});
The analyzer used in both cases, would be this one in the code, above.
Does this mean i would have to create a new Analyzer and reindex the whole
lot?
Bearing in mind ofcourse that there is also a free text element also,
See this becomes the problem, for the tags I would like an analyser that i
can tokenize by space alone since the tags are fed separated by a space,
However for the free text, need that to be the Analyser above .
i.e. Analyzer analyzer = new StandardAnalyzer(new String[]{});
Is it possible to add 2 different fields to the same document using 2
different analysers? thisis to say
field 1 analyser 1
field 2 analyser 2
int he same document ..
Are there any implications wrt to doing this

What analyzers are you using for your queries and your indexing?
StandardAnalyzer (I believe) will break "A.B" into two tokens , so your
index could contain both tags. So what you really have in the index would
be
story1 A C E
story2: A B P Q (note no '.').
searching for B.A would really search for B OR A because of 2 things:
1> the tokenizer (assuming StandardAnalyzer or any other analyzer that
breaks tokens at punctuation) would break the query into two terms.

query.
If you're using different analyzers, this is irrelevant. Also, this
assumes
you're using the query parser.
If you haven't already, I *strongly* recommend you get a copy of Luke
(google lucene luke). It lets you examine your indexes to see what's
actually been indexed and lets you examine queries to see what the actual
search terms are. It even lets you use different analyzers to see how they
behave when it comes to creating a query.
