为什么isnumber搜索不能正确处理给定数据？

Question

I am trying to get Excel to search for a series of keywords in title using the ISNUMBER() search function, but it's bringing back all FALSE , which is wrong. Any help would be greatly appreciated:

I made sure I F4'd the item list -- still wrong

=ISNUMBER(SEARCH(R2,$G$2:$G$22))

Answer 1

Use MATCH:

=ISNUMBER(MATCH("*"&R2&"*",$G$2:$G$22,0))

With the Search set up the way you have it, it will only return the value of the first in the list. You can wrap SUMPRODUCT around the formula:

=SUMPRODUCT(--ISNUMBER(SEARCH(R2,$G$2:$G$22)))>0

But that is more intensive then the simple MATCH.

This assumes that the Keyword that is being looked-up is in R2 and the range $G$2:$G$22 us the list of titles.

If it is the other way around then the SEARCH is backwards and should be:

=SUMPRODUCT(--ISNUMBER(SEARCH($G$2:$G$22,R2)))>0
