Hello Chris,
When I read your email again, I find that I didn't understand it
very well, because although fq works for me now, when I need to
construct the q variable, I run into the same set of questions
and am still not clear :)

1. I didn't understand the part above in your reply. If I search for
samsung camera, the query should be like this in the select URL:
q=samsung+camera
And if samsung is mandatory, the query will be like this: (or not:)
q=+samsung+camera
And the first + will be interpreted as mandatory flag?
2. It seems that + may come from a few different things:
- mandatory flag in Lucene query
- space escaping
- to specify multiple q or fq clauses as in:
fq=+popularity:[10 TO *] +section:0
And I have a hard time assuring myself that they'll work correctly
for me.
In my case, I want to search in a title field and a content field.
And I think the query should look like this in the URL: (no mandatory terms)
q=+title:samsung camera +content:samsung camera
with spaces escaped with +:
q=+title:samsung+camera++content:samsung+camera
Is this correct? I'm very unsure already because of the ++.
3. And if I'm correct, I can do the same query with multiple
q variables in the URL, just like what I can do with fq:
q=title:samsung camera&q=content:samsung camera
with spaces escaped with +:
q=title:samsung+camera&q=content:samsung+camera
4. To simplify it a bit, if I have defined content field as
default search field, the query will be:
q=+title:samsung camera +samsung camera
with spaces escaped with +:
q=+title:samsung+camera++samsung+camera
5. To complicate it a bit, let's say the query is supposed to
search samsung camera in both fields, but samsung in title is
mandatory:
q=+title:+samsung camera +content:samsung camera
with spaces escaped:
q=+title:+samsung+camera++content:samsung+camera
Is this correct?
6. I'm compelled to list both the non-escaped format and the escaped
format above because I can not help thinking that the + may
cause problems :)
