March 2020 Update: You can now also search by custom field in chats.
Heymarket allows searching through the message and contact history in chats. You can search for a specific name, word, phrase, or contact custom field.

You can also search for specific names -- for example, searching for Crissie in the inbox returned the contact for Crissie as well as messages with the word Crissie in them.

The Inbox will return all contacts that have "San Francisco" in their City field:
This search feature is currently available for only the web version of Heymarket.
