Multi-Core Configuration
For a multi-core configuration, you can specify sharedLib='lib' in the section of solr.xml and
place the necessary jar files there.
For more information about Solr cores, see The Well-Configured Solr Instance.
Indexing Encrypted Documents with the ExtractingUpdateRequestHandler
The ExtractingRequestHandler will decrypt encrypted files and index their content if you supply a password in
either resource.password on the request, or in a passwordsFile file.
In the case of passwordsFile, the file supplied must be formatted so there is one line per rule. Each rule
contains a file name regular expression, followed by "=", then the password in clear-text. Because the passwords
are in clear-text, the file should have strict access restrictions.

Examples
Metadata
As mentioned before, Tika produces metadata about the document. Metadata describes different aspects of a
document, such as the author's name, the number of pages, the file size, and so on. The metadata produced
depends on the type of document submitted. For instance, PDFs have different metadata than Word documents
do.
In addition to Tika's metadata, Solr adds the following metadata (defined in ExtractingMetadataConstants)
:
Solr Metadata
stream_name
stream_source_info
stream_size
Description
The name of the Content Stream as uploaded to Solr. Depending on how the file is
uploaded, this may or may not be set
Any source info about the stream. (See the section on Content Streams later in this
section.)
