Searching for multiple text strings in conditional formatting

I am trying to apply a conditional formatting to A1 if it contains a specific text (NOT it's cell value). Is there a way to type a list of the specific text to look for in another column and somehow include a search function in the conditional formula of A1? I have been stuck with this one for a while. I will also need to apply different conditional formats depending on the text contained, and for this I assume that I will need to create a different list for each format, but both the LOOKUP and FIND functions will work only if the cell VALUE of A1 matches the text found in the list, NOT if it only CONTAINS the text. If it is possible, I would appreciate any suggestions or pointers. Thanks

Data validation is for restricting values entered in a cell, not at all what I am trying to do here, but thanks anyway

Pl See fiile.
Formula is
=IFERROR(MIN(IF(ISNUMBER(FIND($G$1:$G$8,A1)),ROW($G$1:$G$8),"")),0)=1
Value 1 For First cell. This to be changed for each condition.

Dear toubab,

See the attached file. Thanks.

Thanks to everyone, but none of these are working for me. I think maybe I didn't make myself clear in the question, so here is a sample of what I am trying to do.

Very good question and if it is up to me, I would use a different conditional formatting, not matter which key words are present. Not sure if it would work though.

Pl See file.
Same Formula is used for CF. If you have more words from the list first word in the string of A cell will be used for CF by the formula.
=IFERROR(MIN(IF(ISNUMBER(FIND($G$1:$G$8,A1)),ROW($G$1:$G$8),"")),0)=1
Value 1 For First cell. This to be changed for each condition.

Thank you for the formula. I see that you changed the Value for each condition, but the formula doesn't work for the other cells. For instance, A1 and A2 were highlighted after the word "computer" was found in the list, but A4 didn't not get highlighted with the match on "technology", same for A6 or A7 with "science". It looks like once the first match is detected, all other CF formulas are ignored, unless I am missing something here.
Many thanks anyway for your input on the first formula :-)

Thanks again, but after playing a bit with your formulas, I noticed that when I change the order of the words in the list in G:G, only the first word (G1) is matched to whatever is found in A:A, the next 4 words are ignored. Is there a way around this?

I changed the values in G column . Still it is is OK. I think you have not typed the words instead cut and paste is done. Delete the words and type other words and check.

I just opened your file, deleted the words in G:G, retyped new ones and it is the same, only the 1st word I type in G:G (G1) gets matched in A:A, the others are ignored (G2, G3 and G4). It seems like we are very close , but not there yet

For each cell from G1 to G8 different colors are chosen for CF.You can verify this putting only word from G1 to G8.

Bingo!!! All I had to do is actually edit one of the CF rules to confirm the cell shade, click OK and apply before all the highlights showed up Thank you very much for your help!!
