Pattern Match - Raw Grep
?
Summary

This tool finds a word, string of text or pattern anywhere within a text document. The results can be displayed as a concordance of words, sentences or lines.

Note: This tool works best when the input is plain text. If an HTML or XML text is submitted, the tool will strip all tags and process it as plain text.

Please click the ? buttons at the bottom right of each set of options for more information on that set.

For further information on this tool, please see the TADA Wiki's Raw Grep entry here. A glossary of terms is also available here.

Summary

This section determines what to search for within the document.

Fields

Pattern
Users can filter results based on the word, phrase or pattern (regular expression) entered here. To search multiple words without the tool treating them as a phrase, separate words with commas (Ex: red, orange, purple). To search for a phrase, enter it as it appears in the text - quotation marks are not needed (Ex: wine-dark sea, not "wine-dark sea").
