Can we search some mandatory words and some optional words in SOLR
Dear SOLR Experts
Llets say I want to search some mandatory words and some optional words.
Say I want to search all documents those contains all *Java, mysql,
php*keywords along with atleast one keyword out of
* TCL, Perl, Selenium*.
*Basically I am looking at few mandatory keywords and few optional keywords.
*
Is it possible to search this way. If so, kindly guide me how the query
should look like.
Best Regards
Kamal

Thanks Hoss, I modified accordingly.
One more thing I observed, if I give search key as one of the below
1. +Java +mysql +php +(TCL Perl Selenium) -ethernet -switching -routing
2. +(TCL Perl Selenium) -ethernet -switching -routing
3. +(TCL Perl Selenium)
It works as expected. Like if key is +(TCL Perl Selenium) , then it
searches documents having atleast one or more keyword out of TCL Perl
Selenium.

Yeah, I keep forgetting that "min should match" for a BooleanQuery defaults
to 1 only if there are no required terms, but if there are required terms it
defaults to 0.

Hi Hoss
I was wondering between this two keys. Though they look similar, but result
set differs.
In 1st case I give key as
+c +c++ +sip +( *tcl* perl "shell script") -"manual testing" -ss7
In 2nd case I give key as
+c +c++ +sip +(*tcl* perl "shell script") -"manual testing" -ss7
Please note that before *tcl* , space is not present in 2nd case.
In 1st case I get more results, and in 2nd case I get only 3 results.
In first case, I see atleast one result was there, which does not have
single optional key (means one document that does not contain either tcl or
perl or "shell script"). Is it a known issue.., please help..
Or I am doing something wrong in key preparation, please let me know.
Thanks
Kamal

That's also part of the basic, traditional Lucene search syntax:
+Java +mysql +php TCL Perl Selenium -ethernet -switching -routing

Your solution having key as* **+Java +mysql +php TCL Perl Selenium* worked
nicely.
If I have to extend it something like, I need to search all documents,
those have
1. Mandatory Keywords present are *Java, MySql*
2. Atleast one keyword out of* TCL Perl Selenium* should be present
3. The keywords *ethernet, switching, routing* should not be present
in document. In that case, how the search key should look like.

That's simply a standard, old-fashioned Lucene query:
+Java +mysql +php TCL Perl Selenium
And you can decide if "min should match" (mm) is 0, 1, 2, 3, etc. for the
optional terms (TCL, Perl, Selenium)
