unexpected result using plain Redis queries in PHP using predis

[johnqiuwan]

Describe the bug
Turn the command

FT.SEARCH idx:product "@product_name_text:eos" RETURN 2 product_name_text category

into

Redis::executeRaw(['FT.SEARCH', $productIndexKey, '@product_name_text:(' . $productName . ')', 'RETURN', '2', 'category', 'product_name_text']) will give null

To Reproduce
Steps to reproduce the behavior:

1. Run command 'FT.SEARCH idx:product "@product_name_text:eos" RETURN 2 product_name_text category' will give expected result
2. Run command using Predis
   Redis::executeRaw(['FT.SEARCH', $productIndexKey, '@product_name_text:(' . $productName . ')', 'RETURN', '2', 'FIELDS', 'category', 'product_name_text']) will give null

Expected behavior
Redis::executeRaw(['FT.SEARCH', $productIndexKey, '@product_name_text:(' . $productName . ')', 'RETURN', '2', 'FIELDS', 'category', 'product_name_text']) should give the same result as run the command 'FT.SEARCH idx:product "@product_name_text:eos" RETURN 2 product_name_text category'
