extended search - search including condition in various forms due to different inflectional endings (stemming), synonyms, omitting diacritical marks etc.
precise search - search only for the condition as specified. Other inflectional endings, synonyms, omitting diacritical marks are not taken into account.
Results may vary depending on the selected search index, so set it according to your needs.
You can affect the results of the search using the following guidelines:
The use of quotation marks forces search for exact phrases, for example, "simple story". In addition, using the ~ character, you can specify the maximum distance between each words, for example, "simple story"~5 - search for "simple story" within 5 words from each other.
Use wildcards if you do not remember the exact phrase that you want to search.
wea? will return results for both words weak and wear
analy* will return results, for example, analysis, analytical, analyze
Wildcard can be used at the end or in the middle of a word.
AND, e.g., simple AND story will return results for both words,
OR, e.g., simple OR story will return results that contain at least one of that words
NOT, e.g., simple NOT story will return results that contain word simple but do not contain word story
We may also use logical operators in more complex query, for example, (simple OR science) NOT chemistry will return results for words simple or science, but do not contain the word chemistry.
