Indexing involves extracting and analyzing the content and metadata of documents to create an index, which is a data structure optimized for quickly searching and retrieving information. Querying: An information retrieval process starts when a query enters the system. A query is a statement that a ...
(to 20 mm) and siftings from crushing and sorting plants is used in wells. Water stemming of well charges is less effective, since its ejection resistance decreases sharply with an increase in diameter. Stemming made with pieces of rock no larger than 300 mm is advisable for case charges....

bigoref.com uses the term “indexing” where bigocheatsheet.com uses “access”. I’ve stuck with “access” for bigoquiz.com. bigoref.com splits array into Basic Array and Dynamic Array, not allowing insertion or deletion in a Basic Array. I don’t find the distinction useful, so I ...
Spatial indices are a family of algorithms that arrange geometric data for efficient search. For example, doing queries like “return all buildings in this area”, “find 1000 closest gas stations to this point”, and returning results within milliseconds even when searching millions of objects. ...
the key step in construction of suffix arrays and the Burrows–Wheeler Transform, two of the most important structures in text indexing and biological sequence analysis [1,2,3]. As such, algorithms for efficient suffix sorting have been the focus of intense research since the early 1990s [4,...
Maximum parsimony (phylogenetics) : an algorithm for finding the simplest phylogenetic tree to explain a given character matrix. Merge sort: sort the first and second half of the list separately, then merge the sorted lists Metaphone : an algorithm for indexing words by their sound, when pronounc...
External sorting algorithms allow for sorting large amounts of data by only considering a small fraction of that data at a time. They are used when the data being sorted do not fit into the main memory of a computing device (e.g. RAM), and instead must reside in the external memory (...
