FileMaker Extra: Indexing in FileMaker

FileMaker Extra Indexing in FileMaker

One of the more significant changes in FileMaker 7 and 8 revolves around indexing. In prior versions, indexing was restricted to 60 characters total, broken into blocks of up to 20-character words. Relationships had to be built around match fields, or keys, that were relatively short and generally nondescriptive. This is one of the reasons why we generally advocate using simple serial numbers for indexing purposes. It's rare that you'd need more than 20 digits to serialize the records in a data table.

In FileMaker 8, words can be indexed up to approximately 100 characters. Text fields can be indexed to a total of 800 characters, and numbers can be indexed up to 400 digits. The limits to indexing have been effectively removed.

What this means to developers is that we can now use far more complex concatenated key combinations (ironically there will be less of that in FileMaker 8, given that data can be related across multiple tables), use longer alphanumeric keys, or, as we suggested earlier, introduce a descriptive elements to keys.

In the past, FileMaker Pro would identify "Special_Edition_Using_FileMaker_8" (32 characters) as identical to "Special_Edition_Using_MS_Access"clearly a terrible mistake to make. It's now possible to match against paragraphs of text or very large numbers. Determining matches will be more exact and finds and sorts more robust.
