That's impressive answer. I actually wanted to know how exactly query
parser works. I'm actually supposed to collect some fields,values,other
related info and build a solr query. I wanted to know i should use this
queryparser or java code to build solr query. Anyway it looks i've to go
with java co
I would say "*:*" is a human-readable/writable query. as is
"inStock:false". The former will be converted by the query parser into a
MatchAllDocsQuery which is what Lucene understands. The latter will be
converted (again by the query parser) into some query. Now this is where
*which* query parse
All right let me put this.
http://192.168.1.78:8983/solr/collection1/select?q=inStock:false&facet=true&facet.field=popularity&wt=xml&indent=true
.
I just want to know what is this form. is it lucene query or this query
should go under query parser to get converted to lucene query.
Thanks,

That's *:* and a special case. There is no scoring here, nor searching.
Just a dump of documents. Not even filtering or faceting. I sure hope you
have more interesting examples.

Hi Daniel,
You said inputs are "human-generated" and outputs are "lucene objects". So
my question is what does the below query mean. Does this fall under
human-generated one or lucene.?
http://localhost:8983/solr/collection1/select?q=*%3A*&wt=xml&indent=true

Alexandre's response is very thorough, so I'm really simplifying things, I
confess but here's my "query parsers for dummies". :)
In terms of inputs/outputs, a QueryParser takes a string (generally assumed
to be "human generated" i.e. something a user might type in, so maybe a
sentence, a set of wo
I am going to have a go at this. Maybe others can add/correct.
When you make a request to Solr, it hits a request handler first. E.g.
a "/select" request handler. That's defined in solrconfig.xml
The request handler can change your request with some defaults,
required and overriding parameters.
Hi,
I think this might be a silly question but i want to make it clear.
What is query parser...? What does it do.? I know its used for converting
query. But from What to what?what is the input and what is the output of
query parser. And where exactly this feature can be used?
If possible please
