List of word sources ordered by precedence
List of added word sources. You can activate or deactivate a word source by checking / unchecking the checkbox in each word source. The source icon shows the type of word source:
-- database source
-- text file source
-- simple list source
The order of the word sources does matter! Higher-placed sources will have a higher precedence when generating crosswords, and vice-versa. For inactive (unchecked) sources, the order of precedence is ignored. You can use the Up and Down buttons in the Toolbar to move the sources and change their priority.
Double-clicking a word source brings up the Word Source Editor to let you change its parameters.
If checked, this option lets you constrain the number of matching words found during crossword generation. This option boosts generation performance when the active word sources aggregate to a very large dataset. When unchecked, no search result truncation will be made, and pycrossword will handle ALL the matches it finds.
Used in with the activated Constrain max results option, this box allows you to fine-tune the number of results yielded by the search engine (for each target word). The default value is 500.
