 ### Fuzzy match (`?`)
 
-By prefixing a search term with `?` a fuzzy matching algorithm will be used to match the search term against the index.
+By prefixing a search term with `?` a fuzzy matching algorithm will be used to match the search term against the index. You can optionally specify the maximum edit distance and maximum number of sequential edits
+for a specific search term using the format:
 
-#### Defaulting search terms to fuzzy matching
-
-By default LIFTI will treat a search term as an [exact word match](#exact-word-matches), however [you can configure the index](../index-construction/withqueryparser/#configuring-the-default-lifti-queryparser) so that any search term (apart from those containing wildcards)
-will be treated as a fuzzy match.
+`?{max edits},{max sequential edits}?term`
 
-#### Fuzzy matching
+For example `?2,1?food` will search for "food" with a maximum number of edits of 2, and maximum sequential edits of 1.
 
-LIFTI uses [Levenshtein distance](https://en.wikipedia.org/wiki/Levenshtein_distance) to perform fuzzy matches between a search term and tokens in the index.
-The distance between two words is the number of edits that are required to match them, including:
+You can omit one or the other parameter if required, so `?2,?food` will only set the maximum number of edits to 2, leaving the maximum sequential edits at the default value.
 
-* insertions: fid would match fi**n**d 
-* deletions: foood would match food
-* substitutions: frnd would match f**i**nd
-* transpositions: fnid would match f**in**d - Transpositions are a special case, because although two characters are affected, it is considered a single edit.
+See [Fuzzy Matching](../fuzzy-matching) for more details.
 
-The resulting Levenshtein distance between any matched term and the search term is used to reduce the score of the match. This means that documents containing
-words that are closer matches will typically be surfaced higher up in the search results.
-
-To prevent a [combinatorial explosion](https://en.wikipedia.org/wiki/Combinatorial_explosion) of potential matches, LIFTI currently limits the maximum number
-of allowed edits to 3, and sequential edits to 1. This means that as of now:
+#### Defaulting search terms to fuzzy matching
 
-* **feed** will *not* match **food** because it requires two sequential edits
-* **redy** will *not* match **friendly** because it requires 4 insertions
+By default LIFTI will treat a search term as an [exact word match](#exact-word-matches), however [you can configure the index](../index-construction/withqueryparser/#configuring-the-default-lifti-queryparser) so that any search term (apart from those containing wildcards)
+will be treated as a fuzzy match.
