Prediction Source "History" does not use all of the PSReadline history #5014
Description
Activity
I have another example of it failing, without having done Set-PSReadLineOption -MaximumHistoryCount
In this screenshot, on the last command, PSReadline should match on one of the 'New-Alias c cNameFetch' lines in the history file, and suggest the auto-completion; but it does not.
There are about 146,361 lines in the file, and in the example given here, that line exists as line 136,549
When typing 'New-Alias ', an auto-completion for a different line is suggested.
(gc $BigHistFile).Count
146361
Are maybe both of these problems just due to this low (default) setting?
[PSReadLine seems to me to be scanning further back than 100 commands.]
(Get-PSReadLineOption).CompletionQueryItems
100
Reacted by NebulaSorry; I found the Set-PSReadLine documentation, and the -CompletionQueryItems is irrelevant.
