How to query similar records in SQLite database from Android?

Let's say an SQLite database column contains the following value:

U Walther-Schreiber-Platz

Using a query I'd like to find this record, or any similar records, if the user searches for the following strings:

• walther schreiber
• u walther
• walther-schreiber platz
• [Any other similar strings]

However I cannot figure out any query which would do that. Especially if the user does not enter the - character.

Example:

select * from myTable where value like '%walther schreiber%'; would not return the result because of the 开发者_JAVA技巧missing -.

Thanks, Robert

So, as I said in my comment, I think you can have a query along the lines of:

select * from myTable where LOWER(value) like <SearchValue>

I'm assuming you're collecting the <SearchValue> from the user programmatically, so would be able to do the following: <SearchValue> would need to be: The user's search string, appropriately cleansed to avoid SQL injection attacks, converted to lower case, with all of the spaces converted to '%', so that they match zero or more characters...

So you would have (for example):

select * from myTable where LOWER(value) like '%walther%schreiber%'
select * from myTable where LOWER(value) like '%walther-schreiber%platz%'

etc... however, this does assume that the word order is the same, which in your examples it is...
