Instant search - triggering a search event manually

We are developing an angolia based instant search implementation.
Our search interface uses this interface
We’d like to trigger the search as soon as a tag appears after the entry of a search term

Our current approach is to add search terms to a hidden field then to try and trigger instant search

Is there are nicer way of doing this - we’re new to Algolia

Thanks very much for any tips
Kind regards

Hi @us1 can you tell us what flavour of instantsearch you’re using? (vanilla, react, angular or vue ?)

Youcef - thanks for your response
We’re using vanilla js at this time

Further to our post - We think that we just want a way of adding to search terms programmatically using instant search. Has anyone needed to do this?
Thanks for any tips
