I would like to be able to access the full capability of the Solr search engine. One example of this would be to build a query that utilizes a color range to select images that have a certain color to help me build aesthetically pleasing web pages with content that matches. In addition, I would like to be able to select images of a certain size so that I know I will not be stretching images when embedding in external applications. All of this should be available in the WCH asset and content picker. I should also be able to create stored queries so that I can select groups of images that have a common theme without having to specify filter parameters for every search request. The stored search queries should also be available in the content picker.
