Abstract: Described herein are methods and systems for pattern recognition in web search engine result pages. The input data is a result page from a web search engine as well as an integer number for the results on the page. The output is a regular expression that matches all the results on the page, capturing each result and its individual fields.

Abstract: Systems and methods to provide filter hints for a result set are provided. In example embodiments, a search request is received and a search is initiated. Documents retrieved from the search are analyzed to determine filters, which may be organized into filter groups. A filter count for each filter is determined. The filter count indicates how many documents match the filter within a current result set or how many additional documents match the filter if selected. The current result set is a set of remaining documents based on any number of previously selected filters from any one or more filter groups being applied thereto. In example embodiments, the filters include enabled filters and any disabled filters, whereby the disabled filters have a zero filter count in the current result set. A visual indicator may also be provided to indicate at least one filter being selected within a collapsed filter group.
