> Key: SOLR-5124
> URL: https://issues.apache.org/jira/browse/SOLR-5124
> Project: Solr
> Issue Type: Bug
> Components: update
> Affects Versions: 4.4
> Environment: Windows 7 (don´t think, this is relevant)
> Reporter: Christoph Straßer
> Priority: Minor
> Labels: tika,text-extraction
> Attachments: 01_alz_2009_folge11_2009_05_28.pdf, 02_PDF.png, 03_TikaOutput_GUI_MainContent.png, 03_TikaOutput_GUI_PlainText.png, 03_TikaOutput_GUI_StructuredText.png, 03_TikaOutput.png, 04_Solr.png

> For some kind of PDF-documents Solr glues words at linebreaks under some circumstances. (eg the last word of line 1 and the first word of line 2 are merged into one word)
> (Stand-alone-)Tika extracts the text correct. Attached you find one sample-PDF and screenshots of tika-output and the corrupted content indexed by solr.
> (This issue does not occur with all PDF-documents. Tried to recreate the issue with new word-documents, I converted into PDF on multiple ways without success.) The attached PDF-document has a real weird internal structure. But Tika seems to do it´s work right. Even with this weird document.
> In our Solr-indices we have a good amount of this wird documents. This results in worse suggestions by the Suggester.
