This topic explains the rules for string construction from words.
- Max. Compare Distance
- This feature allows you to extract a search string from a word, neglecting a certain number of characters at the beginning and at the end. The compare distance computes as follows. Compare Distance = 1.00 - Number of Characters (Search String) / Number of Characters (Word) A match requires that the actual compare distance is less or equal the maximum compare distance.
- Max. Wordcount
- Allows you to extract strings that consist of multiple words.
- Max. gap between words
- Specifies the maximum distance in mm that permits word concatenation during the search. Note that the requirements strongly depend on font size.
- Max. Candidate Length
- Specifies the maximum length in mm a candidate is allowed. A candidate that exceeds the maximum length is not accepted.
- Compare case sensitive
- Select this option to make the candidate search case-sensitive.
- Keep spaces between connected words
- By default, the engine deletes spaces between connected words. To keep the spaces, select this option and enter the spaces in your format string.
| Format String | Keep spaces between connected words | Found phrase | Extracted |
|---|---|---|---|
| "Phrase1Phrase2" | Off | "Phrase1" "Phrase2" | "Phrase1Phrase2" |
| "Phrase1Phrase2" | On | "Phrase1" "Phrase2" | No |
| "Phrase1 Phrase2" | Off | "Phrase1" "Phrase2" | No |
| "Phrase1 Phrase2" | Off | "Phrase1Phrase2" | No |
| "Phrase1 Phrase2" | On | "Phrase1" "Phrase2" | "Phrase1 Phrase2" |
| "Phrase1 Phrase2" | On | "Phrase1Phrase2" | No |
