In "Lucene In Action" book it says it is better practice to combine two
fields into one field and index it than use the MultiFieldQueryParser.
Do I initially index both the fields and then index them again together?
When I index them together do I index the fieldnames or values? Can
someone giv

Erik,
What is generally the reason for indexing both individual fields, and the
general-purpose "content" field ?
Also, if we search in the general-purpose "content" field, wouldnt this
problem occurs. Let say we have 2 fields and the following values:
name : John Smith
food : subway sandwich
: What is generally the reason for indexing both individual fields, and the
: general-purpose "content" field ?
so you can explicitly query for "name:paris" or "city:paris" instead of
just "paris"
: name : John Smith
: food : subway sandwich

Erik's has used a space as the field separator. May be you can use a
different field separator that your analyzer won't eat up, so that will
change the token position by 1.

Yeah, I used a cruder form by appending all the text together into a
single string with a space separator in that LIA example.
Given the position increment gap between instances of same-named
fields that is now part of Lucene, I recommend using multiple field
instances instead.

Thanks for everyone's help. I understand how it works now. I can get rid
of MultiFieldQueryParser in search.
thanks

Did you mean ... recommend "NOT" using multiple field ?
If we want to do query like "name:John" or boasting of Fields ... then we

How do you set the position increment gap between each addition to the
same field name. Should you set it as high as possible to prevent
proximity queries from crossing it? I have been looking for the code to
find out how to put a gap between each same name field addition, but I

it does't have an explicit setter, you just subclass that Analyzer of your
choosing and override getPositionIncrementGap to return the value of your
choosing -- it could be a fixed value, or your Analyzer could be
