# Classify

enaio® uses the smart FIX component from Insiders to classify documents. Aside from the restrictions and guidelines set out by the software maker, the following recommendations are proven best practices:

smart FIX requires additional databases located on an MSSQL server. System sizing will vary depending on the daily volume of incoming data. At least 1 GB RAM and one CPU on the MS SQL server should be reserved for smart FIX. The classification component is deployed on a dedicated host and requires resources in line with the volume of documents. As a rough guide, it can be assumed that 20 to 30 seconds will be required to extract one A4 page (150 dpi) if you are using a 3 GHz CPU. This is a worst-case scenario, which is a reasonable assumption considering the scanned originals to be processed, the quality of the scanned originals, and other use of infrastructure. Processing typically takes less time. The specified RAM usage is 1 GB per CPU core.

It is possible for one CPU to process roughly 20,000 pages per month.

Here's why: 20,000 page/20 working days/eight hours per working day/60 minutes = 2.08 pages/minute; this can be handled by a single CPU core.

The example above assumes a highly constant flow of incoming documents. If large batches of documents are received by the system during certain weeks or months, the requirements will change based on the demands in terms of processing speed. As a further example, it is assumed that the documents generated during a month (20,000) need to be processed in a single day (eight hours).

In short: 20,000 pages/eight hours/60 minutes = 41.7 pages/minute. 20 CPU cores will in turn be needed for processing by the classification system.

The key variable is thus the desired processing speed, taking into account the intermittency of incoming documents. Scaling must be carried out on this basis.

Navigation | Navigate through the help pages using the table of contents on the left. If it is not displayed when the window width is small, you can temporarily show it via the hamburger menu on the right. Use the arrows on the toolbar to navigate to the next/previous page. You can show hidden areas. Use the toolbar to show all hidden areas at once:
--- | ---
Clicking the product icon in the header returns you to the beginning of the current area. Use the toolbar to access the initial page:

Full-text Search | The search does not feature case sensitivity. A search term is also found as part of a string. Multiple search terms in the exact order as entered will be found if they are enclosed in quotation marks (").
--- | ---
Boolean Operators | You can use the following Boolean operators:
AND | Finds the pages that contain all search terms. Spaces, '+', and '&' function the same.
OR | Finds the pages that contain at least one of the search terms. The pipe character (|) functions the same.
You can combine search terms and Boolean operators using parentheses. Example: Paul AND (Peter OR Meyer)
The current portal area is used for the search. You can use Google to search through all portal areas. Example: follow-ups site:help.optimal-systems.com
