any idea how can i batch delete with array of ids

You can use delete by query end-point: https://typesense.org/docs/0.20.0/api/documents.html#delete-by-query

i saw that but couldn't find all the option for the filter_by field

You can do

filter_by=field_id:[100, 101, 102]

etc.

documents().delete({ 'filter_by=field_id': [1000, 1006] })

gives 400 error, is it right ?

What is the error message returned?

this

It must be like this:

client.collections('companies').documents().delete({'filter_by': 'field_id: [1000, 1006]'})

SyntaxError: Unexpected token ':' tried to do nest it inside a curly braces too that gives a parse err

There was a typo in my earlier snippet, fixed it now.

Server said: Could not find a filter field named

field_id

in the schema. ...but i didn't add id in schema ..should i ?

Yes

ohh, i thought i don't need to add ids ...🙃

IDs are treated specially and currently not indexed. So you have to add them as an additional field if you want to do this.
