How to search if whole word exists in a String in Postgres

Question

I have a table with a column field that has values like Samsung Phone.

My question is how can I get this row if I search for a string \"Samsung\" or \"phone

Answer 1

Also you can use this:

title ~* '(^|[^\w])samsung([^\w]|$)'

The advantage of the above one is, it can be easily extended to include characters from different encoding like this: (Turkish characters)

title ~* '(^|[^\wğüşıöçĞÜŞİÖÇ])samsung([^\wğüşıöçĞÜŞİÖÇ]|$)

Here is a sample case where you may need the above extension.
For example; in a Latin5 encoded database you have a value of 'İsamsung'. İ is the capital of i in Turkish.
In this case the title ~* '(\msamsung\M)' does not work. This criteria returns the İsamsung value. Because in Latin5 encoding, postgre thinks İ is out of alpanumeric range and the value is something similiar to :samsung.
