I wish to install Apache Solr on my small linux machine, and am wondering basically can do the installation with yummy. yum list prints all available packages, but you can't really go through 1000's of those to obtain the right install, especially thinking about a package might be named virtually anything.

It is possible to better method to discover if your particular package can be obtained with yummy?

Two options (given that they both often return spun sentences)

yum search solr
yum list | grep solr

I see just the PHP wordpress plugin on my small machine, but I am utilizing an older release.

Need much more, you are able to perform a filename match on things with solr inside them:

yum provides */*solr*

Try:

yum search solr

Whether it does not think it is, you will need to include more databases.
