Expression sources are the source of the data being aggregated in <<analytics.adoc#expressions,analytics expressions>>. | ||
|
||
These sources can be either Solr fields indexed with docValues, or constants. | ||
|
||
== Supported Field Types | ||
|
||
The following <<field-types-included-with-solr.adoc#field-types-included-with-solr, Solr field types>> are supported. | ||
Fields of these types can be either multi-valued and single-valued. | ||
|
||
All fields used in analytics expressions *must* have <<docvalues.adoc#docvalues,docValues>> enabled. | ||
|
||
|
||
// Since Trie* fields are deprecated as of 7.0, we should consider removing Trie* fields from this list... | ||

.Multi-valued Field De-duplication | ||
[WARNING] | ||
==== | ||
All multi-valued field types, except for PointFields, are de-duplicated, meaning duplicate values for the same field are removed during indexing. | ||
In order to save duplicates, you must use PointField types. | ||
==== | ||
|
||
== Constants | ||
|
||
Constants can be included in expressions to use along side fields and functions. The available constants are shown below. | ||
Constants do not need to be surrounded by any function to define them, they can be used exactly like fields in an expression. | ||
|
||
=== Strings | ||
|
||
There are two possible ways of specifying constant strings, as shown below. | ||
|
||
* Surrounded by double quotes, inside the quotes both `"` and `\` must be escaped with a `\` character. | ||
+ | ||
`"Inside of 'double' \\ \"quotes\""` \=> `Inside of 'double' \ "quotes"` | ||
* Surrounded by single quotes, inside the quotes both `'` and `\` must be escaped with a `\` character. | ||
+ | ||
`'Inside of "single" \\ \'quotes\''` \=> `Inside of "double" \ 'quotes'` | ||
|
||
=== Dates | ||
|
||
Dates can be specified in the same way as they are in Solr queries. Just use ISO-8601 format. | ||
For more information, refer to the <<working-with-dates.adoc#working-with-dates,Working with Dates>> section. | ||
|
||
* `2017-07-17T19:35:08Z` | ||
|
||
=== Numeric | ||
|
||
Any non-decimal number will be read as an integer, or as a long if it is too large for an integer. All decimal numbers will be read as doubles. | ||
|
||
* `-123421`: Integer | ||
* `800000000000`: Long | ||
* `230.34`: Double |
