Add a search box to content management option

Guess that's something for D7, but it is a good idea!

This should be independent of the search.module's UI, but dependent on search.module being enabled (due to requirement of active search indexes)

This is a good feature request. The request is to add a keyword filter to the content overview page on admin/content/node. This would let you display unpublished pages containing the keyword "foo", for example. Sending the keyword into do_search seems like a reasonable option. Instead of putting this in system module with an if(module_enabled('search')) I'd recommend putting it in search module's formalter implementation.

I don't think the search module would really be necessary. Probably the biggest use case would be to search for a keyword in the node title, and this could pretty easily be accomplished with an additional filter in the filters section, without the search module.

Anyway, I think it's an excellent idea.

If someone is adding filters to admin/content/node, how about adding a filter for a date range (on created and/or updated date) as well? Or should I file a different issue for that suggestion?

See this discussion of a totally revamped filtering section for admin/content/node in the Usability group: http://groups.drupal.org/node/18008

features at this point are for D8

#1279652: Add title search feature on the node listing admin page was marked a duplicate of this, although it probably has more info. Unfortunately that itself was closed duplicate of #497804: [meta] Search entities (nodes, terms, etc.) within the administrative interface (which is disputed :). @jhodgdon: this later issue works with node title search, so that should be matching your expectations. Marking this duplicate for that then.
