By default, dtSearch indexes numbers both as text and as numeric values, which is necessary for numeric range searching. Use this flag to suppress indexing of numeric values in applications that do not require numeric range searching. This setting can reduce the size of the index by about 20%.
dtsoTfSkipXFirstAndLast = 0x0002
Suppress automatic generation of xfirstword and xlastword. By default, xfirstword is defined to be the first word in each document, and xlastword is defined to be the last word in each document. These words are generated when an index is created, so this flag must be set during indexing to suppress xlastword and xfirstword.
Automatically insert a word break around characters in the Chinese, Japanese, and Korean Unicode ranges. This makes it possible to search text in documents that do not contain word breaks. Like the hyphenation setting, this setting is kept in the alphabet for an index and so will only change when an index is created. See Alphabet Settings.
dtsoTfXmlAsText = 0x100
Index XML files as text, without applying field attributes to the content.
dtsoTfDatabasesAsText = 0x200
Index database files (*.dbf, *.csv, *.mdb, and *.accdb) as text, without applying field attributes to the content or separating rows into separate documents.
dtsoTfHideRevisions = 0x800
Remove strikeout text and redlining from Microsoft Word documents edited using "Track Changes".
dtsoTfHtmlSkipNav = 0x1000
Skip navigation sections of HTML files (<nav>...</nav>)
dtsoTfHtmlIgnoreNoIndex = 0x2000
Ignore BeginNoIndex and EndNoIndex tags in HTML
dtsoTfUseEmailDateAsFileDate = 0x4000
Use internal message date as file date for standalone .eml and .msg files
dtsoTfUseIcu = 0x8000
Enable use of ICU for Unicode processing. See "ICU Integration" for more information.
When indexing MIME messages, if a text or HTML message part has a Content-Disposition header specifying that it is an attachment, then treat the content as an attachment rather than rendering the content inline.
