I'd like to get any comments about how I might do this - I have list some o=
ptions below, which of course I'll investigate...

Example first:
Name Field
--------------
Mr. Youness Rokven

Mr. Joe Paul Harry Arnold

Mr. Paul B. Mitchell

Mrs. Fernanda Joe Mitchell

Ms. Jade Paula Victoria Muir

Mr. Joe Harvey Pope


If I search the above with text such as "Joe P.H. Arnold" which is turned i=
nto a query:
((Joe) or (P) or (H) or (Arnold))

I get hits:
Mr. Joe Paul Harry Arnold

Mrs. Fernanda Joe Mitchell

Mr. Joe Harvey Pope


And the scores are great! The top hit having a higher relative score.

What I'd like to do is exclude hits where say less than 2 terms matched the=
 document field terms.

Options I think:

1.)    Overide DefaultSimilarity?

2.)    Construct awkward searches, example:

((Joe) and (P)) or ((Joe) and (H)) or ((Joe) and (Arnold))   etc ... all th=
e possible combinations

3.)    Use TermVector information? Don't know much about this, but my thoug=
ht is that if highlighting knows the matching terms,...perhaps I use that?

Would be grateful for comments.
Thanks!
