rest api: where do I find list of searcher classes?

[mirek paszkowski]

Searching on a created custom field using jql gives error:

error  "Field 'cf[10024]' is not searchable, it is only sortable."

I understand this to be result of not defining a searcher for the field, so where do I find a list of available searchers?

The field was created with:

"type": "com.atlassian.jira.plugin.system.customfieldtypes:textfield"

I have found field type definitions here:

https://bobswift.atlassian.net/wiki/spaces/CSOT/pages/41287807/Custom+Field+Types

By the way, the table is missing :textfield - which I am using for a simple text field, I just need to find the searcher for it.  (I'm guessing the class is  TextSearcher, just need to know how to define it when creating the field)

After a bit of guesswork, we have success!

create custom field as below.

{
    "name": "test-for-search",
    "description": "Custom field for testing search",
    "type": "com.atlassian.jira.plugin.system.customfieldtypes:textfield",
    "searcherKey": "com.atlassian.jira.plugin.system.customfieldtypes:textsearcher"
}

To those that still end up in this page, since Atlassian hasn't yet provided proper documentation or improvements on their API, the best way to figure out the types and searcher keys is by reading the existing ones directly from the jira database:

SELECT DISTINCT [CUSTOMFIELDTYPEKEY],[CUSTOMFIELDSEARCHERKEY]
FROM [jiradb].[jiraschema].[customfield]
WHERE CUSTOMFIELDTYPEKEY LIKE '%customfield%'

Hello, 

Navigate to the Custom Fields page, locate the desired custom field and choose cog icon > Edit.

Unfortunately that does not help as we need to configure as much as possible using the REST API without having a user log in to the JIRA web app.

Somewhere on my searches, I found example of creating a custom field, and there is a seacherKey field (here: https://docs.atlassian.com/jira/REST/cloud/?_ga=2.158266362.171452215.1508917703-1204457752.1498574522#api/2/field-createCustomField

{
    "name": "New custom field",
    "description": "Custom field for picking groups",
    "type": "com.atlassian.jira.plugin.system.customfieldtypes:grouppicker",
    "searcherKey": "com.atlassian.jira.plugin.system.customfieldtypes:grouppickersearcher"
}

- this is what I believe I am missing - and hence asking for the values of type and searcherKey for all supported field types.

I have found Javadoc for custom fields and it is possible the value is the name of the class, but all in lower case, so it may be a case of try it and see what happens.
