Related Topicsĭocument filters overview: Document Filters and Supported Data If a single file is larger than 2Gb and does not appear to be in a recognized container format, dtSearch will handle it as a unrecognized binary file and use the filtering algorithm to extract text from the file. If a file is too large to be processed using available memory, the file will be skipped and the name recorded in the log of indexing errors. dtSearch uses efficient memory management to handle even very large files. Individual documents can be up to 2Gb in size and will be indexed fully. dtSearch can index files larger than 4gb in these formats. dtSearch does not limit the number of indexes you can create.Ĭontainer file formats such as ZIP, MBX, PST, and CSV have no specific size limit. File size limitsĪ single dtSearch index can hold up to 1 terabyte of text. In some ambiguous cases, such as distinguishing XML and HTML files, the extension is used as a clue. For example, a Word document named 'sample.exe' would still be identified as a Word document. File type identificationĭtSearch generally detects file formats by examining the actual file contents, not the extension or reported MIME type, so it is not affected by misleading filenames. All file formats are supported through the current release versions, unless otherwise noted.ĭtSearch file format support is included with all dtSearch products and can also be licensed separately - for information, please contact dtSearch. dtSearch uses its own built-in document filters for document parsing and display, unless otherwise noted. dtSearch converts other file types to HTML for display with highlighted hits. dtSearch developer products can display XML files with XSL formatting.

PDF files are displayed using Adobe Reader and a dtSearch plug-in to enable hit highlighting.

HTML and PDF documents appear with all formatting and embedded images and links intact, exactly as in the original document. Embedded Object and Attachment ExtractionĭtSearch can automatically recognize, index, search and display documents, including graphic marking of hits and multiple hit and file navigation options, in the file formats listed below.Searching for dates, email addresses, and credit card numbers can be substantially faster because you can search for a single unique expression instead of having to search for many different variations. Indexing will be substantially slower with the recognition feature enabled. The same syntax used in search requests works in the listing functions, so if you generate a list using 'creditcard(*)', you will get a list of all credit card numbers in the index. In the dtSearch Engine API, you can use ListIndexJob (.NET) or DListIndexJob (C++). To list all dates, credit card numbers or email addresses in an index, you can use the word listing functions in dtSearch Desktop (Index > List Index Contents.). There is no option to separately control whether dates, email addresses, and credit card numbers are recognized. In the dtSearch Engine API, set the flag dtsoTfRecognizeDates in Options. In dtSearch Desktop, click Options > Preferences > Indexing Options, and check the box to 'Automatically recognize dates in text.'

To enable it, set Options.matchDigitChar to '='.Įnabling automatic recognition of dates, email addresses, and credit card numbers The = wildcard is disabled by default in the dtSearch Engine.
