Filters

Filters give you the ability to process value of fields before indexation. Filters are separated each others by colons (:) and may have optional arguments separated by commas (,). Multiple filters can be chained. The output of one filter is applied to the next.

List of filters:

Filter	Signature	Syntax	Description
strip	strip()	strip	Strip HTML. It can be useful for excerpt and content value to not index HTML tags and attributes.
truncate	truncate(start: number, end: number)	truncate,0,300	Truncate string from start index to end index. Algolia has some limitations about record size so it might be useful to cut post contents.

Example

1  fields:
2    - content:strip:truncate,0,200

It will strip HTML from content value then truncate the result starting from index 0 to index 200 before indexation. This property will be added to algolia records as contentStripTruncate
