    copied!<p>I am using Solr through PHP for searching all aspects of my site. I am trying to implement a feature and can't find any information on how to accomplish it.</p> <p>I have a group of documents (reviews), each about a specific product.</p> <p>I want to find unique 1-2 word keywords (no stop words) that appear in multiple reviews for a single product, with a count for how many reviews they appear in.</p> <p>Once I have that, I want to show the top X keywords, number of reviews they are in, and a single top review for each one highlighted the use of the keyword.</p> <p>EDIT:</p> <p>Once I have a list of unique (non stop word/common words) keywords that appear in multiple reviews, I want to rank them by the number of times they appear across reviews. For example, if people are writing reviews about cameras, the keywords might appear like this:</p> <p>expensive (appears in 7 reviews) shutter speed (appears in 5 reviews) poor image (appears in 3 reviews)</p> <p>Once I have those keywords ranked by number of reviews, I want to select 1 review per keyword and show those reviews highlighting the keyword. For example:</p> <p>"... unfortunately this camera is far too EXPENSIVE for what you get ..." (in 7 reviews) "... the SHUTTER SPEED is far too slow for ..." (in 5 reviews) "... the POOR IMAGE quality is tis cameras biggest downfall ..." (in 3 reviews)</p> <p>As far as when to run this, I'm still not sure. Possibly real time (when you view a product, then cached for X time), whenever a new review is posted, mark the product to be updated, or on a cronjob daily, etc. It will not be run against all keywords at one time, it will be run against all keywords in all reviews for a single product. Then repeated for each product.</p> <p>Hope that makes more sense.</p> <p>Any help on how to accomplish this in Solr would be greatly appreciated.</p>
