Hi all,

Is there a way that I can replace my Startswith function with 'Contains' or 'Substring' in PowerApps?
Report Owner Name: Joe Smith

Report Number: R2021/07

So that when I search in 'Smith' or '2021' or '07' the Gallery can return the desired results.

Thank you.

If(

!IsBlank(
LookUp(
'Report List',
Title = varUserName
).Title),
Sort(Filter('Report List', varUserName = 'Report Owner Name' || 'Report Status'.Value = "Complete"),
StartsWith('Report Owner Name', InpSearch.Text)|| StartsWith('Report Number', InpSearch.Text)
),
else statement

)

Or can I just use 'Search' function?

Hi @Australia ,

Firstly the top filter needs to return less than 2,000 records (and your delegation setting at this) for this to work as the in filter is not Delegable

If( !IsBlank( LookUp( 'Report List', Title = varUserName ).Title ), With( { wList: Filter( 'Report List', 'Report Owner Name' = varUserName || 'Report Status'.Value = "Complete" ) }, Sort( Filter( wList, InpSearch.Text in 'Report Owner Name' || InpSearch.Text in 'Report Number' ) ), YourSortFieldHere ), else statement )

Fantastic, thanks @WarrenBelz. Could you tell me what the 'With' function does in this incidence?

And correct, my list only has about 500 rows of data (less than 2000).
What is the advantage of using 'With' over 'Search' function highlighted in blue below?
If(
!IsBlank(
LookUp(
'Report List',
Title = varUserName
).Title),
),
Sort(
Search('Report List', InpSearch.Text,"Report Owner Name", "Report Number", "Report Date")
,
'Report Date',
Descending
), else statement

Hi @Australia ,

I have explained it in this section of one of my blogs, but it creates a (very) temporary table which must be under 2,000 items (With() is a "hidden" Delegation limitation) which you can then filter in the rest of the statement without any Delegation issues as it is no longer querying the data source directly.

Thanks @WarrenBelz A little bit advanced for me to comprehend. 🤔
So I just applied your formula and it has no red lines. But the gallery did not return any results though. Not sure what happened here?

Hi @Australia ,

Can you please post the exact code (in Text) you have used and also how many items are in the list. I assume you have records in your list where the Title field is your user name?

Thanks @WarrenBelz.
Here's the full syntax:

If(
!IsBlank(
LookUp(
'Report List',
Title = varUserName
).Title
),
With(
{
wList:
Filter(
'Report List',
'Report Owner Name' = varUserName || 'Report Status'.Value = "Complete"
)
},
Sort(
Filter(
wList,
InpSearch.Text in 'Report Owner Name' ||
InpSearch.Text in 'Report Number'
)
),
'Report Date',
Descending
),
Sort(Filter('Report List', varUserName = 'Report Owner Name' || 'Report Status'.Value = "Pending"),
StartsWith('Report Owner Name', InpSearch.Text)|| StartsWith('Report Number', InpSearch.Text)
)
);

Hi @Australia ,

I assume you had something in the Search box? Anyway try this

With( { wList: Filter( 'Report List', Report Owner Name' = varUserName || (Title = varUserName && 'Report Status'.Value = "Complete") || 'Report Status'.Value = "Pending" ) }, Sort( Filter( wList, IsBlank(InpSearch.Text) || ( InpSearch.Text in 'Report Owner Name' || InpSearch.Text in 'Report Number' ) ), 'Report Date', Descending ) )

Fantastic, thanks very much @WarrenBelz !
By the way can I have two 'With' functions in the syntax?

For the else statement at the last of the syntax, can I use another With
where I want to filter the list varUserName = 'Report Auditor Name'
