infoRouter - Enterprise PDF Full-text search
[infoRouter] Whilst infoRouter is designed to use a document's, custom property set as the main search/retrieval criteria it also has a full-text search capability which leverages MS Index Server. MS Index server requires a third-party i-filter to be installed to catalogue the contents of a text pdf. In most cases, the i-filter provided by Adobe™ as a free download is sufficient from http://www.adobe.com/downloads/
However, it may be that in the 64bit Enterprise environment that it should be upgraded with a more powerful i-filter. One such is the PDFlib TET PDF IFilter 4.1.
A trial download is available.
