SearchImprove has some advanced spell checking and language features.

SearchImprove is able to use a number of language settings that may provide better search results for your site.

Stemming

The Stemming feature expands the search to include all grammatical inflections of the search term. Searching for mouse also finds mice.

Wildcard search

This checkbox can be ticked to enable wildcard search. The wildcards are:

• *: Replaces one or more letters. Searching for peac* finds peach, peaches, peaceful, peace etc.
• ?: Replaces a single letter. Searching for rec??ve finds the misspelled recieve and the correctly spelled receive.

Right truncation

Right truncation automatically applies a multi-letter wildcard at the end of the search term, without any user action.

By enabling right truncation, a search for page also matches pagelist, pager, pages, pageant etc.

Dictionary

Selects a dictionary to use for spell checking actions.

Spell checking

Selects a method and a presentation mode to perform spell checking actions the available options are:

• No spell checking: The users search query is not checked against the dictionary.
• Automatic spell checking: If a suggestion exists for the current search term, the search engine automatically performs a Boolean OR search for the search term OR the suggestion.
• Automatic spell checking when 0 results: If a suggestion exists, and the user's search query did not match any documents, the search engine automatically searches for the suggestion.
• Did you mean?: If a suggestion for the current search term exists, it is presented in the familiar Did you mean ...? form.
• Did you mean?: If a suggestion for the current search term exists and the user's search query did not match any documents, the suggestion is presented in the familiar Did you mean ...? form.

Number of suggestions:

Selects the maximum number of suggestions presented to the user. Note that this is a maximum number; the search engine can only display as many suggestions as the dictionary provides.

Assemble search words:

This feature is particularly useful for languages that join compound nouns, which is the case for most Germanic languages. If this checkbox is ticked, searching for multiple search terms also performs a search for those search terms with spaces between words removed.
