Identifiers name program entities such as variables and types.
An identifier is a sequence of one or more letters and digits.
The first character in an identifier must be a letter.

Cgo first invokes gcc -E -dM on the preamble, in order to find out
about simple #defines for constants and the like. These are recorded
for later use.

Next, cgo needs to identify the kinds for each identifier. For the
identifiers C.foo, cgo generates this C program:

	void __cgo_f_1_1(void) { __typeof__(foo) *__cgo_undefined__1; }

#### API-Based Migration

**Step 1: Extract Documents**

Use your current system's API or export functionality to extract:
- Document URLs or identifiers
- Document content/text
- Metadata (title, author, date, etc.)
- Security/access control information

**Step 2: Format for Fess**

Create NDJSON file with required Fess fields:

```json
