Text Filterer is an advanced desktop full text searcher. With TF, you can instantly search for single words, partial words, Boolean word combinations, and exact or proximity phrases within hierarchically organized collections of documents. Classic Explorer-like interface allows you to easily browse a search result by folders, switch between found documents viewing their contents in the preview pane, and navigate through the found words highlighted in text. Search results can also be narrowed by file name, type, location, date/time, size, title, author, etc. You create search queries as filters usable across sessions. Switching between filters gives you an efficient way to explore the contents of a collection. TF supports plain text, Unicode, RTF, XLS, HTML, PDF, and uses MS Word and PowerPoint (if installed) to index DOC, WPD, PPS, PPT and other MS Word supported files. TF supports many image formats such as BMP, ICO, GIF, TIFF, PNG, JPEG, PSD, WMF and more. TF searches, browses and extracts supported files stored in ZIP, RAR, MHT and CHM archives at any level of nesting. With Excel files having same columns, TF provides an option to selectively search by Excel columns and rows presenting search results in one view. TF shows search results in the list view, with documents (or their parts called snippets) as rows, and their attributes as columns. Column data of a search result can be saved to a tab-delimited text file for later processing with a spreadsheet or database application. Yet another option is to copy/extract resultant documents to a folder with or without conversion of them into plain-text copies. TF has built-in support for working with multilingual texts. Advanced features include selective searches by used-defined data fields established around a common regular structure of documents, if any, and chopping documents into snippets to make them units of your searches instead of entire files, if they can be structurally subdivided into such snippets.
