Recently the search does not crawl all pages in the various Pages Libraries in our SharePoint 2010 based Extranet. For example, in our German Technical Catalog which consists of 2085 Pages only 377 items get crawled.
The pages get generated automatically and have the same schema. Except for some values inside an XML file, they are basically the same.
There are no errors in the Crawl Log that could point to any problem. The strange thing is that the Technical Cataloge for Italy is fully crawled. All 2000+ items are crawled within the Index.
I can't detect any reason for this error.
