Apache Solr Reference Guide Covering Apache Solr 6.0

stream_content_type
The content type of the stream, if available.
We recommend that you try using the extractOnly option to discover which values Solr is setting for
these metadata elements.
Examples of Uploads Using the Extracting Request Handler
Capture and Mapping
The command below captures tags separately, and then maps all the instances of that field to a dynamic
field named foo_t.
bin/post -c techproducts example/exampledocs/sample.html -params
"literal.id=doc2&captureAttr=true&defaultField=_text_&fmap.div=foo_t&capture=div"
Capture, Mapping, and Boosting
The command below captures tags separately, maps the field to a dynamic field named foo_t, then
boosts foo_t by 3.
bin/post -c techproducts example/exampledocs/sample.html -params
"literal.id=doc3&captureAttr=true&defaultField=_text_&capture=div&fmap.div=foo_t&boo
st.foo_t=3"
Using Literals to Define Your Own Metadata
To add in your own metadata, pass in the literal parameter along with the file:
bin/post -c techproducts -params
"literal.id=doc4&captureAttr=true&defaultField=text&capture=div&fmap.div=foo_t&boost
.foo_t=3&literal.blah_s=Bah" example/exampledocs/sample.html
XPath
The example below passes in an XPath expression to restrict the XHTML returned by Tika:
bin/post -c techproducts -params
"literal.id=doc5&captureAttr=true&defaultField=text&capture=div&fmap.div=foo_t&boost
.foo_t=3&xpath=/xhtml:html/xhtml:body/xhtml:div//node()"
example/exampledocs/sample.html
Extracting Data without Indexing It
Solr allows you to extract data without indexing. You might want to do this if you're using Solr solely as an
extraction server or if you're interested in testing Solr extraction.
The example below sets the extractOnly=true parameter to extract data without indexing it.
