Q: How to get SOLR working on magento ce 1.7.0.2 How to get SOLR working on magento ce 1.7.0.2
Why i need SOLR:
I need to use SOLR to reduce my +10seconds loading time on searches. I know there is also sphinx, but i don't like that one.
I have followed instructions from here:
install SOLR:
http://inchoo.net/ecommerce/install-apache-solr/
what to do next:
magentocommerce.com/boards/viewthread/301508/ (i followed the 2nd post, but i cannot find the conf from step5. i assume i only need to use the schema.xml from the extension and paste it into the conf folder in the SOLR installation)
used this extension:
code.google.com/p/magento-community-edition-solr/
Magento version: 1.7.0.2
SOLR version: 4.6.0
Running on VPS (CentOS 6.4)
magento-community-edition-solr: 1.1.4
SOLR is running and i can access the Solr Dashboard. I have set the settings in magento system/configuration/Solr Search Engine to my settings like host/path and port. 
Problem:
I re-index the catalog search indexes and here starting the troubles. I can see activity on my server (mysql. i assume data is re-indexed into the magento database) but when indexes are re-indexed in the sql database i assume it needs to re-index data to/for Solr, right? The "in progress" won't stop and i see nothing been added to Solr collection.
When i use the searchbox on my site i get a 400 error "400' Status: Bad Request" I also see some activity in putty when i search on my site, so i think the connection between magento and Solr are OK. If there is no connection i assume Solr cannot do stuff whn i trigger the magento search. No results found because the 400 error so i get the default magento search results.
What i think:
I think the problem is in the conf folder (schema.xml). When i use the default schema.xml i get the error "undefined filed store_id". So i need to map the store_id, i know. So i use the schema.xml that i can find in the solr magento extension. When i upload that file i only get more errors and Solr won't work at all.
What i have done:
Replaced and edited schema.xml over and over again. Searched google and found people with the same problem but no answers for this problem.
More questions:
When i installed Solr i find out that there is a collection1 "core selector". I don't see anything about that in the install instruction of Solr or the Solr extension. Maybe because my Solr version is newer as used in the tutorials? BUt that collection1 i use to store the conf folder with the schema.xml file. In the tutorials people talk to paste conf folder into example folder, but my structure is example/collection1/conf. Am i wrong?
How does magento knows what collection it need to use? I think here is something i need to edit (or not) or do i need to add the collection1 to the Solr path i use in the magento extension configuration?
Thanks
edit 1:
I have installed (uploaded) solr version 3.4.0 and transfered the schema.xml from the magento extension to the conf folder from solr 3.4.0. I already see 1 problem. The standard schema.xml shows this <schema name="example" version="1.4"> and the schema from magento extension <schema name="example" version="1.5"> i ignored that and headed on. Solr errors and won't start. I removed the new schema and use the standard schema. Error when i start solr "store_id is not a fallid field or something". So i have put the filed code from magento schema.xml into the solr schema.xml.
Yes! Search is FAST! But shows no results. hits=0 status=0
I need to tell that the reindex from the catalog search is still running/processing and won't finish and i don't see documents or data added to the solr data/index folder (if that is where documnets are stored).
Another problem is that solr now only runs when i keep the shell connection open. When i close putty, solr will stop. I think this can be solver by using a other command to start solr. Maybe this is a red flag for a other problem, so i mentioned this ;-)
edit 2:
I have installed solr for the 3th time, now with this instructions:
ctdev.co.za/magento-solr-search-setup-for-community-edition-solr-ce/#comment-86
WHen i reindex the search catalog by shell i get this after a couple minutes:
PHP Fatal error:  Allowed memory size of 536870912 bytes exhausted (tried to allocate 7 bytes) in /home/admin/domains/test.com/public_html/lib/Zend/Db/Statement/Pdo.php on line 253

Fatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 7 bytes) in /home/admin/domains/test.com/public_html/lib/Zend/Db/Statement/Pdo.php on line 253

Is this error related to the solr index problem?
It still won't put data into solr :(
I have enlarged the memory and now i see this when re-indexing:

I cannot find the data in the solr data index folder. Meybe i need to look somewhere else, but when i search on the shop there are no results :(

A: DONE!
see last edits from my question. I have added the field product_id to the schema.xml file in the conf folder from solr. The stuff is indexed and i can use the solr search feature (great).
Search pages are now loaded within 4-5seconds before 10-15seconds. Time to optimize the reultpage :-)
Thanks for the support!

A: I think the problem is in schema.xml and solr version. Once I tried to use solr 4.x.x for magento enterprise and got many problems because of not compatible schema.xml. 
So if you read Support Matrix for Solr and Magento EE you will see that magento supports only 1.4.1 to 3.4.0 versions.
My advice, try to install Solr 3.4.0. Installation instructions you can find here.
