Posted on by ChLowden

Hello

I have a sharepoint data source that has about 600 entries that are a hard drive and LTO library. Each entry corresponds to either a hard drive or LTO.

Screenshot from 2020-09-29 08-39-18.png

I use a simple power app to filter the 600 entries using :

SortByColumns(Filter([@'200722_RAY_DD_LTO_DB'], StartsWith('CONTENU DISQUE', TextSearchBox1.Text)), "Title", If(SortDescending1, Descending, Ascending))

When I filter by LTO number or other simple entry, I get results back.

But the most important field for me is the disk content field. This contains lists of all the folders each entry has. When I filter this column, I don't get any results back.

All I have read concerning delegation explains that the limit is based on not exceeding 2000 unique entries and it does not mention anything about filtering large text data fields.

Can anyone help me either with an alternative filter or search mode or other soultion?

Many thanks

Hi @ChLowden ,

Could you please share more details about your issue?

How did you filter the disk content field? please share the code.

What is the date type of disk content field? Does it store a table with all folders each entry has?

If so, I would suggest you use the following code. use in operator to check if the search text contains in the disk content table.

SortByColumns(Filter([@'200722_RAY_DD_LTO_DB'], TextSearchBox1.Text in 'disk content'), "Title", If(SortDescending1, Descending, Ascending))

Note: this formula may not be delegable, but it won't make any influence since there are only 600 entries if you increase the delegation limitation to 2000 in PowerApps Settings.

If this doesn't make sense, please share more details about your issue.

Hope this helps.

Hello Sik
To be honest, I don't understand. My goal is to search all the CONTENU DISQUE cells in the sharepoint for text strings using the search field at the top of the app's window.
Attached are screen grabs of the sharepoint & the power app canvas.
Many thanks

I don't understand why (maybe you can tell me), but this seems to work.

SortByColumns(Filter([@'200722_RAY_DD_LTO_DB'], TextSearchBox1.Text in 'CONTENU DISQUE'), "Title", If(SortDescending1, Descending, Ascending))
Many thanks
