![]() ![]() Middle-hand Truncation: User avoid to use some character from the middle of the term and create stem and search for information, i.e.As far example, the truncation ‘tion’ may retrieve all terms with the same suffix like examination, information, application etc. Its possible to retrieve all homo-terms, by adding necessary prefix at the beginning of the word. ![]() Left-hand Truncation: In this truncation stem formed by excluding the very first part of a word.The truncation ‘IM’ will for example, retrieve documents containing important impossible, impolite, import etc. In a sample words, right-hand truncation ignoring the end of a word. Right-hand Truncation: Right-hand truncation refers to the ability to search on the initial string of characters in a word.Three types of truncation are commonly recognized which are being: Term Truncation Search Logic: Truncation is another SL which is to be found chiefly in the computerized full-text, free language information retrieval system.If the document has been indexed under both terms A and B, then it will be printed out even it has also been indexed under term C because (13-6=7), which is the threshold value. Any of these or all.” Such a broad generalized request can be visualized as follows:ĭocuments indexed under term B will be printed out only, if term C has not been used too. in logical some Boolean search, we should say, “ give me any document that deals with drugs or that deals with pneumonia or that deals with cat. It means that we want any document that is related to any one of the topics under circumstances consideration, i.e. Through logical sum we may gather lots of information in a certain subject. Logical Sum (OR) or (+): The first operator of Boolean SL is ‘OR’ or logical sum.Three types of operators which are describing details in the below: In the year of 1858 English Mathematician George Book devised a system of symbolic logic, in which he used three operations (+, ×, -). This search logic used to gather lots of information. Boolean Search Logic: In searching Boolean search logic is one of the efficient methods.Types of Search Logic: Ordinarily, search logic is three in types which are briefly being: Thus, search logic is the means of specifying the combination of terms which must be matched for successful retrieval. To make a knot between and amongst these terms there use search logic. In retrieving information, there use several specific terms. The methods of search depend on purpose and demand of information. Search Logic: Information is meant to be searched. There are different types of search logic which all are different from each other but they all helps to find information in a convenient way. To reduce this problem there are use some search techniques or search logic to find a specific information or document easily. In this information era, it is very difficult to search a specific document from the huge amount of document. ![]()
