3. PROPER QUERY SYNTAX

Search as one expression:

If between the search terms no any other word should be present, then include the search term in double quotes: "Ավետիսյան Արա".

Wildcard Searches:
? – The single character wildcard search looks for terms that match that with the single character replaced. For example: Շիրա? will retrieve the documents with the terms Շիրակ, Շիրազ.
* - Multiple character wildcard searches looks for one or more characters. You can also use the wildcard searches in the middle of a term. For example: բան*ր will retrieve the documents with the terms բանվոր, բանբեր, բանաձևեր, բանավոր
You cannot use a * or ? symbol as the first character of a search.

Boolean operators:
The AND operator matches documents where both terms exist anywhere in the text of a single document. The symbol && can be used in place of the word AND.
To search for documents that contain Համբարձումյան and մեխանիկա use the query: “Համբարձումյան” AND “մեխանիկա”.
The OR operator links two terms and finds a matching document if either of the terms exist in a document. The symbol || can be used in place of the word OR. To search for documents that contain either Մծբնի or just Հյուսիսային use the query: “Մծբնի” OR “Հյուսիսային”.
The NOT operator excludes documents that contain the term after NOT. The symbol ! can be used in place of the word NOT. To search for documents that contain Մծբնի but not Էջմիածին use the query: “Մծբնի” NOT “Էջմիածին”.
The „+” or required operator requires that the term after the “+” symbol exist somewhere in the field of a single document. To search for documents that must contain Մծբնի and may contain Էջմիածին use the query: +Մծբնի Էջմիածին.

Grouping:
You can group clauses using parentheses to form subqueries. To search for either Համբարձումյան or մեխանիկա and Դիլիջան use the query: (Համբարձումյան OR մեխանիկա) AND Դիլիջան.
This eliminates any confusion and makes sure that Դիլիջան must exist and either term Համբարձումյան or մեխանիկա may exist.

Fuzzy searches:
To do a fuzzy search use the tilde, “~”, symbol at the end of single word term. For example to search for a term similar in spelling to անձրեւ use the fuzzy search: անձրեւ~. An additional parameter can specify the required similarity. The value is between 0 and 1, with a value closer to 1 only terms with higher similarity will be matched. For example: անձրեւ~0,8. The default that is used if the parameter is not given is 0,5.
