Issue | Solution |
Noisy search results | Implemented searches supporting keyword “all” or “any” limiting the number of matches: MSEARCH-91 |

Bug in sorting by title | |
Support phrase search | |
Ranking refinement | Refinement of the default ranking system will require further analysis to be in the scope of a separate feature |
Discrepancy in saving UUIDs from Action menu | MSEARCH-93 and UISEES-58 |
UI enhancements and bug fixes | UISEES-47, UISEES-57, UISEES-61, UISEES-62, UISEES-48, UISEES-49 |
Two evaluators determined that the POC did not meet their expectations and provided the following reasons:
...
| Query | mod-inventory (PostgresSQL), s | Results Count | mod-search (Elsasticsearch), s | Results Count |
|---|---|---|---|---|
keyword all "April" sortby title&limit=100&offset=0 | 4 | 37408 | 1 | 41268 |
*keyword all "April" sortby title&limit=100&offset=1001 | 5 | 37408 | 1 | 41268 |
