How to 'compose' live queries

[browze]

Just wondering if there is a particular recommended way/facility in the lib for composing live queries (i.e. combining existing live queries with different filters, with the result being a live query). Perhaps as already outlined in the following post?:

Live queries produce Observables that can be composed using helper libraries such as RxJS. But even better to compose them using promises, async functions and await (only compose the actual queries in separate async functions and compose them as if you only wanted a single return value, and were unaware of liveQuery, when call these composed functions from your live query).

Thanks. If I've understood you correctly, the second approach you've recommended would be to pre-compose the 'querier' argument to liveQuery from the component functions you want. For example, start with the 'base' query, which might be db.[table] etc and then separate 'filter' functions that would process the promise returned by that base function. Then pass that to liveQuery as the 'querier'.
