Easy PDF Search indexes your PDF files and allows you to search your files for keywords. When you perform a search in Easy PDF Search, it first scans your library paths for PDF files. New and modified files will be indexed, then only existing files are searched.
In some situations, you may not have the source PDF files with you, but only the Easy PDF Search index database. Or you may not want Easy PDF Search to spend time scanning for existing files, but just want to search for keywords in the already indexed files.
In Easy PDF Search 2.1, we added the option to skip the file scanning process and directly search the existing index. This is available under the Options menu.
Selecting the Search index only option will search the existing index and return the results, regardless of whether the file exists.
To recap the 4 options:
- Index new files only
This option scans the search folders defined in each library, and indexes only the new and modified files it finds, then searches for keywords in those indexed files that exist.
- index all files
This option scans the search folders defined in each library and indexes all the files it finds, deleting any existing index for each file. It then searches for keywords in those indexed files that exist.
- search only indexed files
This option scans the search folders defined in each library for files, and searches for keywords in those indexed files. It ignores any new or modified files.
- search index only
This option performs searches on the existing index, and does not scan to check if the indexed files exist.
