X1 Desktop Search helps to find the files, emails, and contacts that are stored on one's hard drive or SSD. After entering text in the search box, X1 consults its index to find "hits" in the file contents or file name.
I've been using X1 for about seven years. Whenever I've had problems with the software, customer support has always been responsive, even if you don't subscribe to the $19.95/year for premium support. Once, the support representative conferenced in one of the developers in order to resolve an indexing problem I had. Review collected by and hosted on G2.com.
I would hope that, at some point in the future, X1 would incorporate frequency of the query terms into its search algorithm. For example, a document that contains more occurrences of a query term should be ranked higher than a document that has a lower frequency of the query terms. Right now, the results are ranked by date, not query term frequency. Review collected by and hosted on G2.com.
