Without knowing anything about baloo this looks totally wrong

QList<KFileMetaData::Extractor*> exList = m_extractorCollection.fetchExtractors(mimetype);

why would not you want to iterate over all the iterators that support a given mimetype?

It's a waste of time. Extractor should store file content in DB for fast access when file content search is performed, so if more than one extractor performs a file it will result in high cpu usage and huge transaction size in DB, basically file content * num of extractors, at least we loose time and disk size for nothing.

Repository: baloo


Processing large directories, +5000 files, can be CPU eater. Large file, itself, can be another issue.
