File Formats Supported by TREX
Documents whose content and attributes can be indexed and searched by TREX can exist in numerous different file formats. The TREX preprocessor converts the document text and attributes of the different file formats into UTF-8 encoded HTML. The file filters of a special filter software are used to enable the subsequent searching and indexing of all prevalent file formats such as MS WORD; MS PowerPoint, PDF, and HTML.
The table below lists all file formats that are currently supported by TREX.

Special Features of HTML Files and XML Files
TREX processes HTML files and XML files without filtering, because the conversion to HTML is not necessary. In principle, the lexicon software integrated in TREX ignores the text of the mark-up elements of the actual HTML and XML code, which is located between the tag brackets ( <...>). In this way, texts such as font size, color, and so on within the tag <font size="7" color="#FF0000"> are not passed on for indexing because this information occurs in many HTML files and thus is not characteristic for the respective document content.
Using the mark-up elements, you can configure which texts within HTML and XML documents should not be indexed. For example, this makes sense in the case of JavaScript program code, which is marked in HTML by the tags <script type="text/javascript"...> ... </script>. The JavaScript program code itself does not contain any characteristic content for the document in question and can thus be ignored.

Special Features of Compressed File Formats (Archives)
The document content of files that are contained in an archive can only be indexed if TREX knows the file format of the files in question. The system uses the filter software to identify the type of files in the archive and filters the file content according to the file type identified. All files in an archive are handled as one large document.
The filter software may sometimes incorrectly assign file types that it does not recognize in an archive to the wrong file type and filter them as such. For example, binary files (*.bin), the content of which was filtered by accident and then indexed, fill the index created with a large number of terms that make no sense.
You can respond to this issue in two ways:
-
You can exclude compressed file formats (archives) from processing by the preprocessor by removing the corresponding MIME type (for example, application/zip) from the TREXValidMimeTypes.ini configuration file.
NoteFor more information about this procedure, see Excluding File Formats from Processing.
-
You can modify the filter software configuration file, default.tpt, in such a way that the names, but not the file content of the files that the archive contains are indexed.
NoteFor more information about this procedure, see SAP Note 900742.
