Containstring takes ages

[selpaqm]

Hi,

i have a calculated column contains containstring. it works however each refresh take hours with more than 1000 rows. normally my table has more than 400k rows. so is there any way to speed it up with changing another think.

if (Countx (filter (Table2, CONTAINSSTRING (Table2 [ID], Table1 [ID])), Table2 [ID])> 0, "Yes", "No")

also you may find entire example on below link

@selpaqm - Perhaps try SEARCH or FIND instead of CONTAINSSTRING?

@Greg_Deckler  thanks for your suggestion. when i try to use search, I have get "The search Text provided to function 'SEARCH' could not be found in the given text." error.

"minx(filter(table,search(" does not fit.

Hi @selpaqm ,

I once created a Power Query prototype here. The merging between the two tables can possibly still be optimized.

See attachement.

@mwegener thanks for your work. I think I have trouble on added custom1 (true false contain section) it gives below error.

Expression.Error: We cannot apply operator & to types Number and Text. Details: Operator=& Left=2030691335 Right=

Hi @selpaqm ,

you are trying to combine a text with a number. Both values must first be converted to the data type text.

Hi @mwegener ,

thanks for the solution, I realized and fixed it. waiting to calculation ending, seems all contain column as "FALSE". after calculation hope it will be ok.
