This report is for the instance at issues.guix.gnu.org. The hint under the search field and the online help documentation suggest that "date:" filter can be used to improve the search results.[1] However, the results are different from what is documented. For example, there is a report submitted on 16 February 2022 and a patch submitted on 20 Fenruary 2022 both contaning the word "mumi".[2][3] I can see them at the end of search results when searching for "mumi".[4] But I cannot find them with any of the following: 1. mumi date:20d..now 2. mumi date:2022-02-01..2022-02-28 The first one returns older posts only.[5] The second one returns nothing.[6] And the last hinted filter does return links to the expected issues but also returns other issues which are apparently out of the specified time period and so introduces noise in the search results making filtering less effective:[7] 3. mumi date:1m..today --- [1] https://issues.guix.gnu.org/help#search [2] https://issues.guix.gnu.org/54024 [3] https://issues.guix.gnu.org/54072 [4] https://issues.guix.gnu.org/search?query=mumi [5] https://issues.guix.gnu.org/search?query=mumi+date%3A20d..now [6] https://issues.guix.gnu.org/search?query=mumi+date%3A2022-02-01..2022-02-28 [7] https://issues.guix.gnu.org/search?query=mumi+date%3A1m..today --- Roman
