Apache Solr Reference Guide Covering Apache Solr 6.0

The literal.id=doc1 parameter provides the necessary unique ID for the document being indexed.
The commit=true parameter causes Solr to perform a commit after indexing the document, making it
immediately searchable. For optimum performance when loading many documents, don't call the commit
command until you are done.
The -F flag instructs curl to POST data using the Content-Type multipart/form-data and supports
the uploading of binary files. The @ symbol instructs curl to upload the attached file.
The argument myfile=@tutorial.html needs a valid path, which can be absolute or relative.
You can also use bin/post to send a PDF file into Solr (without the params, the literal.id parameter would be
set to the absolute path to the file):
bin/post -c techproducts example/exampledocs/solr-word.pdf -params "literal.id=a"
Now you should be able to execute a query and find that document. You can make a request like http://loc
alhost:8983/solr/techproducts/select?q=pdf .
You may notice that although the content of the sample document has been indexed and stored, there are not a
lot of metadata fields associated with this document. This is because unknown fields are ignored according to the
default parameters configured for the /update/extract handler in solrconfig.xml, and this behavior can
be easily changed or overridden. For example, to store and see all metadata and content, execute the following:
bin/post -c techproducts example/exampledocs/solr-word.pdf -params
"literal.id=doc1&uprefix=attr_"
In this command, the uprefix=attr_ parameter causes all generated fields that aren't defined in the schema
to be prefixed with attr_ , which is a dynamic field that is stored and indexed.
This command allows you to query the document using an attribute, as in: http://localhost:8983/solr/t
echproducts/select?q=attr_meta:microsoft.
Input Parameters
The table below describes the parameters accepted by the Extracting Request Handler.
Parameter
boost.< fieldname>
capture
captureAttr
commitWithin
date.formats
Description
Boosts the specified field by the defined float amount. (Boosting a field alters its
importance in a query response. To learn about boosting fields, see Searching.)
Captures XHTML elements with the specified name for a supplementary addition
to the Solr document. This parameter can be useful for copying chunks of the
XHTML into a separate field. For instance, it could be used to grab paragraphs () and index them into a separate field. Note that content is still also captured into
the overall "content" field.
Indexes attributes of the Tika XHTML elements into separate fields, named after
the element. If set to true, for example, when extracting from HTML, Tika can
return the href attributes in tags as fields named "a". See the examples below.
Add the document within the specified number of milliseconds.
Defines the date format patterns to identify in the documents.
