The PDF WebSearch program is unsurpassed at handling even extremely complex search requests. PDF WebSearch can handle multiple levels of boolean, proximity, numeric range, phonic, etc.
Query expansion is combinable with any other search feature.
Fuzzy searching PDF WebSearch's proprietary fuzzy searching uses a unique algorithm to find search terms even if they are misspelled. Search fuzziness adjusts from 0 to 10 to correspond to the level of typographical or OCR errors in files. Fuzziness may be added to any other search request. It may be applied to an entire search request or selectively to words within a search request. Variable term weighting PDF WebSearch provides not only the automatic relevancy ranking in a natural language search request, but also the ability to specify relative weights.
