Please, take a look at the Fulltext Search Feature : //www.eserviceinfo.com/fulltext.php?firsttime=true
and leave me your opinion

Fulltext search indexes the content of the documents, not only filenames and data entered on upload, thus allowing
You to find search terms inside the documents text.
You can type in several words, including signs (+ before the word means it is required, - before the word means that
results, containing the word will be excluded)
The data indexed is more than 100 MB plain text, supported compression is zip and rar (multipart files),
supported document types - pdf and plain text.
In the future i plan to support .djvu files and to add antivirus checks .
