Find & Replace: Regex - "replace only first match and ignore others"

Question

Hi SDL community, 
 I'd like to find and capture only the first " text " in each segment and replace it with e.g. " paraghraph " 
 Segment 1: In years of attending school, most of us have dealt with a number of different technical text s , or texts intended to educate the reader in a particular subject or skill through in-depth study and practice text s.(do not capture or even when matched, do no replace this one) 
 Segment 2: Technical text s, such as a chemistry text book or car repair manual text s , which represents any verse or prose work meant to be instructional text . 
 What would be the regex for: 
 Find: ...... 
 Replace: .....

 You could search for this: 
 (?<!\btexts?\b.+)texts? 
 Then replace with this: 
 paragraph 
 Basically a negative lookbehind so you only find the first "text" or "texts" and then "text" or "texts". Replace is simple as you are finding the first occurrence so you just replace it with whatever text you like.

Mea culpa, it should have been ^(.*?)(\btexts?\b)(.*)$
