Complete list of field "type" that Solr supports
Hi Everyone,
I Googled for this with no luck.
Where can I find a complete list of field "type" that Solr supports? In
the sample scheam.xml that comes with Solr 5 and prior version, I am able
to compile a list such as "boolean", "float", "string", etc. but I cannot
find a complete list documented somewhere.
To be clear, here is an example of a type from Solr's schema.xml:
<field name="weight" type="float" indexed="true" stored="true"/>
Here, the "type" is "float". I'm looking for the complete list of
out-of-the-box types supported.
Thanks
Steve

I got it now.
I have to start from <fieldType/> to create my <field/> list. If I want a
list of supported field-types (used in my schema.xml), I have to look at
the "class" attribute of <fieldType/> to get that list. The out-of-the-box
list of field-types is documented in the link you provided:
https://cwiki.apache.org/confluence/display/solr/Field+Types+Included+with+Solr
Thanks

There are FieldType *classes* which can be configured a variety of ways in
your schema.xml, and then reused by different fields -- but the *names* of
those "types" is up to you.
for example: the exact same TriDateField *class* can be configured in your
schema.xml to implement 2 differnet *types* named "date_foo" and
"date_bar" by using different default options (maybe one uses a
non-default precisionStep and defaults to stored="true" while the other
uses the default precisionStep and defaults to stored="faluse") ... those
two diff types can then both be used in your schema...
<field name="last_modified" type="date_foo" indexed="true" />
<field name="pub_date" type="date_bar" indexed="true" />
...and have different behavior.

Re: Complete list of field "type" that Solr supports

Hi Hoss,
I'm confused. If type="float" is just a symbolic name, how does Solr knows
to index the data of field "weight" as "float"? What about for "date" per
this example:
<field name="last_modified" type="date" indexed="true" stored="true"/>
How does Solr applies date-range queries such as:
last_modified:[NOW-1YEAR/DAY TO NOW/DAY+1DAY]
I was always under the impression that there are primitive field-types but
looks like that's not the case?
Thanks
Steve

what you are asking about are just symbolic names that come from <type/>
definitions in the schema.xml -- there is no complete list. you can add
any arbitrary <type name="foo" .../> you want to your schema, and now
you've introduced a new "type" that solr supports.
As far as the list of all "FieldType" *classes* that exist in solr out of
the box (ie: the list of classes that can be specified in <type/>
declarations, that is a bit more straight forward...
