Have you considered using the built-in QueryFilter for this? Why
isn't it sufficient for your needs?

Hi guys!
I was hoping someone here could help me out with a custom filter.
We have an index of emails and do some searches on the text of an
email message and also searches based on the email addresses in a To,
From or CC.
Since we also do searches on a bunch of emails, we created a custom
filter for searches on an array of fields for an array of values.
[code included below]
The problem we're having is that creating a query string like so:
"Message:viagra AND (From:(email1 OR email2) OR To:(email1 OR email2)
OR CC:(email1 OR email2))"
would return results, but our filter combined with a query string of
"Message:viagra" sometimes wouldn't.
One thing I noticed is that when the results do return with the
filter, the email has the format of [EMAIL PROTECTED], but the
one that doesn't has something like [EMAIL PROTECTED]
Also it might have something to do with the storage of the From or To
or CC. We don't parse out the email addresses before storing them.
So sometimes the value of a From/To/CC field might be
"[EMAIL PROTECTED]" or "local <[EMAIL PROTECTED]>" or even
"<[EMAIL PROTECTED]>". Could the carrots be throwing off my filter?
I also wouldn't mind any suggestions to doing this filter better.
Here is the bits method from our custom filter:
---------------------------------------------------------
final public BitSet bits( IndexReader reader ) throws IOException {
BitSet bits = new BitSet( reader.maxDoc() );
for ( int x = 0; x < fields.length; x++ ) {
for ( int y = 0; y < values.length; y++ ) {
TermDocs termDocs = reader.termDocs( new Term(
fields[x], values[y] ) );
try {
while ( termDocs.next() ) {
bits.set( termDocs.doc() );
}
}
finally {
termDocs.close();
}
}
}
return bits;
}
---------------------------------------------------------
Thanks in advance,
Roy.
