Searching consider:

• the search engine is case sensitive
• results include all records containing the search string
  Example: Pleterski returns all records containing Pleterski (such as: Pleterski Andrej, Macháček Jiři Pleterski Andrej)
• marking Precise search makes the search string precise (all fields), putting the search string between the double quotation marks ["] makes precise search within specified field.
  Example: "Pleterski Andrej" matches records containing only those words.
• avoid using double["] and single quotation marks [']
• unknown characters within the search string can be replaced by either a question mark [?] or an underscore [_]
  Example: Bo?i? matches all words starting with Bo, followed by any single character, followed by i, ending with any single character.
  The result contains records with Božič Dragan as well as Bonis B. Eva or Bosio L.
• unknown strings within the search string can be replaced with a percent sign [%] or an asterix [*]
  Example: Bo% matches all words or groups of words starting with Bo, followed by any number of signs (including zero)
  The result contains records with Božič Dragan as well as Bošković Djurdje and Bojan Djurić.

Searching using logical operators:

• The search string is parsed from left to right where NOT is validated first, followed by AND, OR or XOR (which all have the same priority).
• Query strings validation can be alterd by using parenthesis which can also be nested.
• Precise/not precise switch applies to searching with logical operators as well.

• NOT:
  Flips the logical value of an operand.
  Example: NOT Pleterski in the field Author and 4 in the field Number results in all records containing Number 4 without those with Pleterski in the field Author.
• AND:
  The expression is true when both operands are true.
  Example: Pleterski AND NOT Macháček in the field Author, results in all the records in which the field Author contains Pleterski but not Macháček as well (so Pleterski Andrej but not Macháček Jiři, Pleterski Andrej).
• OR:
  The expression is true if at least one of the operands is true.
  Example: Pleterski OR Macháček in the field Author results in all the records in which the field Author contains either Pleterski or Macháček.
• XOR:
  The expression is true only if one of the operands is true and the other is false.
  Example: Pleterski XOR Macháček in the field Author results in all the records in which the field Author contains either Pleterski or Macháček but not both.
