* I have on the server in
/opt/solr-5.5.1/contrib/extraction/lib all the .jar
files, does this means i have the compiled version ? And where do I add the source
to the complied version?
* And do i need to go trough all this guide ?

* Here is my complete procedure, tested a few minutes ago:
* ```
wget http://archive.apache.org/dist/lucene/solr/5.5.1/solr-5.5.1.tgz
tar xvf solr-5.5.1.tgz
solr-5.5.1/bin/solr start
solr-5.5.1/bin/solr create -c wpsolr-5.5.1
(download solr 5.xx config files from http://wpsolr.com/releases/#1.0)
cp solrconfig.xml schema.xml solr-5.5.1/server/solr/wpsolr-5.5.1/conf/
(reload index with solr admin UI)
(configure a new index in wpsolr admin UI:
Index name: wpsolr - local 5.5.1
Solr Protocol: http
Solr host: localhost
Solr port: 8983
Solr path: /solr/wpsolr-5.5.1
)
(index posts on wpsolr admin UI, including a pdf file)
(search in posts, retrieve the pdf)
```

* Thanks, but now im getting
* Solr HTTP error: OK (404) Error 404 Not Found HTTP ERROR 404
Problem accessing /solr/berotec/select.
* I saw in a previous post in this forum i should edit my path, where do i do that,
i looked in solrconfig.xml but dont find where.
* One more thing, on my local environment i can access mysite:8983 but not on production,
can i reload index without solar admin UI ?

* Within your Solr admin UI, select your index, and query it. It will show you
a full url like
* ```
http://localhost:8983/solr/berotec/select?q=*%3A*&wt=json&indent=true
```
* Is it ?

* i cant access my solar admin on my production site, i dont know why, it times
out. Maybe it has some port forwarding.

* I think portforwarding, but dont know much about it, anyway
In another post
here, it says:
* > I didn’t have to put in the entire path:
> /opt/solr/server/solr/hitlink It
> ended up being: /solr/hitlink
* Where do i edit this ?
