search: allow advanced filters#1995
Conversation
The search key is opaque to the system. Interpret the prefix marker _q=1 as the beginning of an advanced query, allowing to filter on specific fields, e.g.: _q=1&[email protected]¤cy=USD It is the responsability of the user to add relevant indexes.

Simple solution to work around lack of implicit casting on PostgreSQL. Good enough for now? Signed-off-by: Pierre-Alexandre Meyer <[email protected]>
This allows us to find all open and paid invoices for instance. Signed-off-by: Pierre-Alexandre Meyer <[email protected]>

Is the use case that we have to show (return) invoices matching specific balance criteria for the given tenant - and not for a specific account?

Yes, the use-case is to filter invoices for that tenant and balance criteria, e.g., show me all unpaid invoices.
There is a branch in the code because it doesn't support additional filtering capabilities: it's either balance filter or any other filter. Cannot do: show me all unpaid invoices in the last month unfortunately. We might be able to do it, it's just a bit hard with the balance specific query...

The result(s) we return will match the criteria, but since we just return the columns (fileds), the exact balance will not be returned, is this correct - i.e. balance computation is just used for search criteria and not to populate the objects being returned?

Correct.
since we just return the columns (fileds)
That's a good point, I need to check if the objects are re-hydrated at higher levels of the stack or if I should select more columns here.

I am just wondering if we could use the amount computed from the underlying invoiceBalanceQuery() so we don't have to rehydrate the invoices as it is very expensive. However, not returning the balance is an issue as well.

We could:
- Modify
InvoiceModelDaoto have abalancefield. This is set only in this new codepath, when computing the balance in SQL (thebalancecolumn from the SQL query should automatically populate it if the getter and setter for balance are added inInvoiceModelDao. - Modify
DefaultInvoiceto have a privatebalancefield. If set during construction of the object (pulled fromInvoiceModelDao),getBalance()returns it, otherwise, it goes through the computation like today.
@reshmabidikar Could you give this a try? When doing searches, the invoices will still be shallow, but when searchInvoicesByBalance is called, the balance should be returned. If this work, we could also look at updating the other search queries to do the same?

It looks like all the InvoiceItemType are present here, so is this needed?

Moving this as 'Ready to review' as we merged #2023 |

@reshmabidikar Could you create a doc PR to add this new search capability - probably slate doc. @pierre Do we have a matching kaui task to use this ? |
Noted, will do. |
