Array Kullan\u0131m\u0131: Daha Okunabilir ve Esnek \u00c7\u00f6z\u00fcmler<\/strong><\/p>\n
PostgreSQL’de array’ler kullanarak,  NOT LIKE<\/code> ko\u015fullar\u0131n\u0131 daha okunabilir ve esnek bir \u015fekilde yazabiliriz.  \u00d6ncelikle, aranan kelimeleri bir array olarak tan\u0131mlar\u0131z.

Ancak, indekslerin her zaman performans\u0131 art\u0131raca\u011f\u0131 garanti edilemez.  Baz\u0131 durumlarda, indeksler sorgular\u0131n \u00e7al\u0131\u015fma s\u00fcresini art\u0131rabilir.  Bu nedenle, indeksleme stratejinizi dikkatlice planlaman\u0131z ve farkl\u0131 indeksleme se\u00e7eneklerini test etmeniz gerekir.  EXPLAIN<\/code> komutunu kullanarak farkl\u0131 indeksleme stratejilerinin performans\u0131n\u0131 kar\u015f\u0131la\u015ft\u0131rabilirsiniz.
