将动态搜索词数组连接到PHP / MySQL中的字符串

Question

Using Laravel 5.3 and MySQL 5.7.17. I store text in a TEXT column (don't know the limit).

**I want to search this text for different variations of different words in different languages that should lead to the same match.

Example:**

'bird' -> bird

'Vogel' -> bird

'pájaro' -> bird

Try #1: Set up a table with two columns:

• c1 containing the string 'bird'
• c2 containing a serialized array with all alternative search terms. Then, search the large text for all alternative search strings of the unserialized array.

Advantage: only need one table Disadvantage: serialize and unserialize data all the time - bad performance?

Try#2: Set up two tables, one containing the real, right search terms I am gonna use for my code. The second containing all alternative search terms that are linked via a 'One to Many' relationship in Laravel.

Then search for all terms in the second table and, if found, give me a match for the corresponding real string in the first.

Advantage: probably better performance Disadvantage: two different tables.

Since I am dealing with words that don't always have a close connection to each other, I can't rely on stuff like spell checker.

want to manage library of the alternative search terms manually anyway. Is there a better solution to do this?

Answer 1

How about 1 table:

• c1 contains an indexed list of the possible search terms
• c2 contains the standardised search term

I guess that VARCHAR would support better indexing than TEXT. Is there an upper limit that you could impose (50 characters? 100 characters?)?

| c1       | c2         |
|----------+------------|
| bird     | bird       |
| vogel    | bird       |
