"Did you mean" function is based on the index ( all words in search) to create a fictitious " glossary ". This "glossary " is then used to - through the lexical rules and word Strategy - locate "Did you mean"- proposals for different keywords
Note that the " dictionary " is not a general dictionary so you can just get suggestions for words that appear in the search index .
Also note that it may take a while before word recently introduced in the search index can be found in the " Glossary " .
Here's how the settings related to the development of the proposal.
This setting ensures that the predictive be accessed and processed only if a search produces no results found.
A more costly alternative (compares to above) that lead to alternative words must always be prepared - regardless of the number of search results. This option can be useful if the website has misspelled words and want to avoid getting these as words.
This is done preferences in terms of the number of proposals to be handled.
How many proposals to be taken forward for further evaluation. The default value is 5.
Although the standard sökmodulerna is to present only a proposal, it is not a good idea to set the maximum number of proposals for a! A low value provides a poor basis to seek out the "best" proposal. A high reading is costly to process.
This setting ensures that the proposals are processed more and the estimated number of hits is calculated. Selection of proposals
Here you can make settings to determine which candidate words (developed under the lexical rules below) is "best". Use the one that is best under the lexical rules This option takes up the word in the dictionary under the lexical rules is most similar to the keyword. Use the one that is most abundant This option starts with taking forward several candidates from the dictionary under lexical rules is most similar to the keyword. Then set a query for each of the candidates and the candidate appearing the most times in the index are considered to be the best word.
Here you can make settings to determine how alternative words to be selected, ie, "what words are similar to this keyword."
Mathematical algorithm to determine whether a word is similar to another. Possible algoritm choices are:
Default is the Levenshtein algorithm.
A value between 0 and 1 used by ordsimilaritets algorithm. The lower the value, the more words (risk of irrelevant words increases), the higher the value, the fewer (risk of no words at all increases). Default is 0.5.
Here you set the settings to ensure that the proposals are correct.
How many searches to be made to ensure that the proposal gives the results. Default is 5.
For an amendment of synonyms and stop word to be activated it requires that the index is reindexed. When you have made all your changes and saved it. Recreate the index by pressing the indexbutton on the Indexing tab. In the window for reindexing , select " Create a new index that replaces the old ".
All "Did you mean" functionality is handled by a Spell Check Component contained in the search engine, Solr. Through SiteVision you can configure values and parameters that affect the component's algorithms and behavior for "Did you mean" proposals. A technical documentation available on, for example, SpellCheckComponent and SpellCheckerRequestHandler.
