Help with query syntax

[matt davies]

Hello everyone

I'm using solr1.1 and more or less the example app that comes with  
the nightly build.


I'm trying to do a search that says

give me all the results where id=news* and any of the other fields in  
the index that contain the search term form the form.


I've created ID's that contain the items type, so I've got news:23,  
documents:45 etc etc.  We want to now search on a particular type.


I'm trying something like this at the moment, just to get a result  
back from one of the other fields in the index.


if request.has_key('q'):
z = request['q']
gog = "id=news* title_t=" + z
print gog
s = SolrConnection(host='localhost:8983', persistent=False)
data = s.search(q=gog,rows='100', wt='python')

Can't get it to return any results though.

I've got Luke and I can see the field names are correct, I think I  
must be getting the syntax wrong.


Any help will be greatly appreciated.

I've worked it out. colons, not = signs :-)

if request.has_key('q'):
z = request['q']
the_url = request.META['PATH_INFO'].split('/')
cat_type = the_url[3]
print cat_type
		gog = 'id: ' + cat_type + '* AND (title_t:"' + z + '"' + ' OR  
body_t:"' + z + '"' + ' OR url_t:"' + z + '"' + ' OR  
contact_name_t:"' + z + '"'
		gog +=  ' OR keywords_t:"' + z + '"' + ' OR metadescription_t:"' +  
z + '"' + ' OR presenter_name_t:"' + z + '"'

        gog +=  ' OR summary_t:"' + z + '"' + ' OR venue_t:"' + z + '")'
s = SolrConnection(host='localhost:8983', persistent=False)
data = s.search(q=gog, rows='100', wt='python')

Works really well

Re: LockObtainFailedException

[matt davies]

quick fix

look for a lucene lock file in your tmp directory and delete it, then  
restart solr, should start


I am an idiot though, so be careful, in fact, I'm worse than an  
idiot, I know a little


:-)

you got a lock file somewhere though, deleting that will help you  
out, for me it was in my /tmp directory

Re: Lock obtain timed out

[matt davies]

I think you do this if you only have one index

true

Check with cleverer bods first though

Re: quick question

I think I remembered

Was it localhost in the jetty.xml addlistener  
section?

Re: How do I secure solr server?

[matt davies]

Hi Mel

One method is to limit the access to the web backend by only having it  
respond to 127.0.0.1.


I'm not certain here but i think do that you need to add the limiting  
access code in your servlet, which may be different.


For instance, we edited jetty.xml in our situation.

I hope this is of some help to get you  started looking, I've probably  
got alot of terminology incorrect there, and some facts :-)


Might help though.

Hi guys,

I run solr on a separate server from the application server and I'd
like to know how to protect it. I'd like to know how to prevent
someone from communicating to the server and also prevent unauthorized
access (through the web) to admin page.

Any help is extremely appreciated!! :)

Thanks,

Mel
