SQL WHERE clause searching for multiple parameters from one field - sql

Question

Essentially I would like the MS Access query to output all records that meet all three of the following criteria:
Expanded_Status = "Eligible but not enrolled"
Hospital = "UHN"
Comments = "transplant" or "tx" or "post-transplant"
The comments field has 3 different versions of the word "transplant" so some fields may have "tx" instead of "transplant" and some records may have "post-transplant" instead of "transplant".
The query below is outputting records that don't match all three of the criteria for some reason.
Please help me modify the query so that I can find only records with all three criteria fulfilled
SELECT [First Name], [Last Name], [Subject ID], Expanded_Status, Hospital, Comments
FROM [Barriers UHN Screen - 2017 Mailing]
WHERE Expanded_Status = "Eligible but not enrolled" AND Hospital = "UHN" AND Comments LIKE "transplant" OR Comments OR "post transplant" OR Comments = "tx";

Answer 1

Building on #Harun24HR 's answer:
SELECT
[First Name], [Last Name], [Subject ID], Expanded_Status, Hospital, Comments
FROM
[Barriers UHN Screen - 2017 Mailing]
WHERE
Expanded_Status = "Eligible but not enrolled" AND Hospital = "UHN" AND
(LOWER(Comments) LIKE "*transplant*" OR LOWER(Comments) LIKE "*post transplant*" OR LOWER(Comments) LIKE "*tx*");
I added two things:
Calling lower on Comments makes sure you are only comparing lower cased string - if someone has "Post Transplant" in the comments, it might not match on "post transplant"
Wildcards * on the beginning and end of the comparison string - this tells Access my comparison string can be anywhere in the comments.

Zuva,
Try this
SELECT
[First Name], [Last Name], [Subject ID], Expanded_Status, Hospital, Comments
FROM
[Barriers UHN Screen - 2017 Mailing]
WHERE
Expanded_Status = "Eligible but not enrolled" AND Hospital = "UHN" AND
(Comments = "transplant" OR Comments = "post transplant" OR Comments = "tx");
Enclosing the Comment section of the where clause in brackets, tells access to evaluate each separately as part of the AND clause.
