## Projects search endpoint

### What’s new?

* Added GET `/projects/search` to query projects using up to two filters joined by `logic` (and/or).
* Supports standard fields (e.g., `status`, `title`, `city`, `type`, numeric/datetime fields) and custom properties by key name.
* Operators: `eq`, `neq`, `gt`, `gte`, `lt`, `lte`, `contains`, `in`, `nin`, `between`, `exists`.
* Pagination and sorting supported via `page_size`, `page`, and `order_by`.

### Parameters

* `prop1`, `op1`, `value1` (required)
* `prop2`, `op2`, `value2` (optional)
* `logic`: `and` | `or` (default `and`)
* `page_size`, `page`, `order_by`

### Value formats

* `in`/`nin` lists:
  * Plain CSV: `value1=ACTIVE,ON_HOLD`
  * Quoted CSV (values with commas): `value1="Last, First",Other`
  * JSON array: `value1=["Last, First","Other"]`
* `between` ranges:
  * Dates: `value1=2025-01-01,2025-12-31`
  * Numbers: `value1=10000,50000`

### Examples

* Status equals ACTIVE:
  * `GET /v1/projects/search?prop1=status&op1=eq&value1=ACTIVE`
* Title contains “Solar”:
  * `GET /v1/projects/search?prop1=name&op1=contains&value1=Solar`
* Status IN (ACTIVE, ON\_HOLD) AND city = Austin:
  * `GET /v1/projects/search?prop1=status&op1=in&value1=ACTIVE,ON_HOLD&logic=and&prop2=city&op2=eq&value2=Austin`
* Custom multiselect includes any of \["1", "Option, with a comma"]:
  * `GET /v1/projects/search?prop1=custom_multiselect&op1=in&value1=["1","Option, with a comma"]`
* Updated within 2025:
  * `GET /v1/projects/search?prop1=updatedAt&op1=between&value1=2025-01-01,2025-12-31`
