Hybrid search: the twin codes

Dose the mix between keyword and vector to satisfy both whoever types the exact code and whoever describes the symptom.

The X200 manual has 2 similar error codes — E-42 (pressure sensor) and E-17 (low water), only one digit apart. Question 1: “code E-42”. Question 2: describes the symptom, without naming the code.

An exact code and a symptom described in other words call for different doses of search. Find the real balance. ⚗️
