Sales Calls and Estimation
For services, we scheduled calls with the sales team and went over features we wanted to have, implementation concerns, etc. At this step, it was important to estimate an annual cost of search service according to the features we want, search rates, potential index size, etc. The final price was an important factor in final vendor decision making. For self-hosted engines, we calculated an estimated hardware quantity required to support the search. Also, estimated a potential ops time required to support search infrastructure which also leads to additional cost.
