PDF doc search II

I edited includes/SpecialSearch.php to make the saved PDFs searchable. This contribution is limited to a small amount of PDFs. When creating the PDFs don ́t use compress text and images in e.g. acrobat distiller. SpecialSearch.php starts 2 AWK-Scripts. These scripts convert the PDFs into strings. These strings are searchable out of the wikisearchmask. Put the scripts searchAllPDFs.sh and searchPDF.sh in your mediawiki includes/ Folder. Tested under mediawiki 1.54 and LAMP.

see PDF doc search for the older not maintained code.

1. In SpecialSearch.php copy and paste the contribution from Edit SpecialSearch.php .
2. You have to edit this line
$output = shell_exec('includes/searchAllPDFs.sh -i '. $s . ' /home/xyz/mediawiki/images'); (Note: change /home/xyz/mediawiki/images to your real server path.
3. Edit Special:Allmessages
4. In MediaWiki namespace you have to add 2 words:
Pdfmatches, Nopdfmatches http://xyz/mediawiki/index.php/MediaWiki:Nopdfmatches http://xyz/mediawiki/index.php/MediaWiki:Pdfmatches for English edit in Pdfmatches: Matches in PDFs in Nopdfmatches: No matches in PDFs for German edit in Pdfmatches: Übereinstimmungen in PDFs in Nopdfmatches: Keine Übereinstimmungen in PDFs
5. User rights
The files searchAllPDFs.sh and searchPDF.sh have to be readable by your apache-user.

Put the content after line 199:
(Note: Contribution starts with ### line)
(Note: replace www.xyz.com with with your domain and replace /home/xyz/ with your mediawiki path)

 if( $titleMatches ) {
 if( $titleMatches->numRows() ) {
 $wgOut->addWikiText( '==' . wfMsg( 'titlematches' ) . "==\n" );
 $wgOut->addHTML( $this->showMatches( $titleMatches ) );
 } else {
 $wgOut->addWikiText( '==' . wfMsg( 'notitlematches' ) . "==\n" );
 }
 }
