[Nitin Kothwal]

Hi sascha,

You can do with boolean query, Take your three queries and OR them with 
boolean clause Occur.should.

Hi,
  
i want to combine two MultiTermQueries.
  
One searches over FieldA, one over FieldB.  Both queries should be combined with OR operator.
  
so in lucene Syntax i want  to search
  
FieldA:Term1 OR FieldB:Term1,   FieldA:Term2 OR FieldB:Term2, FieldA:Term3 OR FieldB:Term3...
  
how can i do this?
  
greetings

Re: Boolean Search Query is not workng

[Nitin Kothwal]

Hi Priyanka

Construct three different termqueries for house, home and flat. Now for 
first two termqueries you can set boost on them by setBoost(float b) 
method of TermQuery class. Now above three termqueries will be clauses 
of your boolean query, with OCCUR.SHOULD and search in normal way. This 
may help you.

Hi ALL

I am  working on a project which uses lucene for searching . I am
struggling with boolean based Query : Actual Scenario is

e.g
  In Query, if I give house home flat
  then
  inside It should search house or home or flat  but I want to give them
with weightage  like house and home  should get high weigh and flat

should

get less then rest.
If document contain Home  .Lucene search should not go for house  and
flat.

I searched on Internet for some good stuff but not able to find any code
sample or proper syntax for reference .


Thanks
Priyanka
