Declaration

public void AddProperty(string name, string value, int minVariations, int maxVariations, int score, int documentIndex, bool saveKeyword, bool exact);

Parameters

key Key used to retrieve the value.
value String value to store in the index.
documentIndex Document where the indexed value was found.
saveKeyword Indicates if we store this key in the keyword registry of the index. See SearchIndexer.GetKeywords.
exact If true, index stores an exact match entry for this word.
score Relevance score of the word.
name Key used to retrieve the value.
minVariations Minimum number of variations to compute for the value. Cannot be higher than the length of the word.
maxVariations Maximum number of variations to compute for the value. Cannot be higher than the length of the word.

Description

Adds a property value to the index. A property is specified with a key and a string value. The value will be stored with multiple variations.

        // Add a property with exact:true, meaning that you can either use is: or is= to search for results
        // These items are given a high score, so they will not be displayed first in the result list.

        // Use exact:false, so color=red won't match any result, just color:red, same for color:yel
        si.AddProperty("color", "red", si.AddDocument("RGB 55"), exact: false);
