Whoosh 2.4.0 Fast, pure-Python full text indexing, search, and spell checking library. Package Documentation Whoosh is a fast, featureful full-text indexing and searching library implemented in pure Python. Programmers can use it to easily add search functionality to their applications and websites. Some of Whoosh's features include: Pythonic API.Pure-Python. Whoosh might be useful in the following circumstances: Anywhere a pure-Python solution is desirable to avoid having to build/compile native libraries (or force users to build/compile them).As a research platform (at least for programmers that find Python easier to read and work with than Java ;)When an easy-to-use Pythonic interface is more important to you than raw speed. Whoosh was created and is maintained by Matt Chaput. This software is licensed under the terms of the simplified BSD (A.K.A.

Search engine indexing Popular engines focus on the full-text indexing of online, natural language documents. Media types such as video and audio and graphics are also searchable. Meta search engines reuse the indices of other services and do not store a local index, whereas cache-based search engines permanently store the index along with the corpus. Unlike full-text indices, partial-text services restrict the depth indexed to reduce index size. Indexing The purpose of storing an index is to optimize speed and performance in finding relevant documents for a search query. Index design factors Major factors in designing a search engine's architecture include: Merge factors Storage techniques How to store the index data, that is, whether information should be data compressed or filtered. Index size How much computer storage is required to support the index. Lookup speed How quickly a word can be found in the inverted index. Maintenance How the index is maintained over time. Fault tolerance
The Xapian Project Elasticsearch: Five Things I was Doing Wrong | gibrown Update: Also check out my series on scaling Elasticsearch. I’ve been working with Elasticsearch off and on for over a year, but recently I attended Elasticsearch.com’s training class (well worth the time and money) and discovered a few significant things that I was doing just plain wrong. Before using Elasticsearch I used Lucene directly, and so a few of the errors I made were due to not understanding some of the things ES does for you behind the scenes. As background, most of the data I’m indexing conforms to the WordPress database schema. 1. For some reason I had neglected to use arrays when creating fileds such as a list of tags attached to a document. Or, for fields that were lists of URLs I just separated them by spaces and used the whitespace analyzer. Using an array of items is a much easier way, but somehow, after initially reading about the array mapping, I completely forgot that it existed. 2. In the end this was a case of premature optimization. 3. 4. 5. Like this: Related
TinyMCE, jQuery and Ajax forms Even thought this really seems easy, I believe there's stuff missing. I'm trying to make jquery and TinyMCE works together in ajax mode (silent submit and reload), but I really can't get anything working... some help would be appreciated. romain May 16, 2008 #1 "tinyMCE.triggerSave();" was all it took. I just wish I read your entry 4 hours earlier :) would have saved the headache. Mark L. ghjghjghj guga Aug 26, 2008 #3 Thanks bro!

Realtime Search: Solr vs Elasticsearch | Socialcast Engineering What is Elasticsearch? Elasticsearch is REST based, distributed search engine powered by the excellent Lucene library. The built in JSON + HTTP API provides an elegant platform perfect for integrating with (ex: the elastic_searchable ruby gem). Why is it better than Solr? First of all, let’s set the record straight: Solr is fast. Unfortunately, it is really easy to break Solr as well. Now throw a few million documents into the index and Solr will be buckling at the knees while Elasticsearch doesn’t break a sweat! It is painfully apparent that Solr’s architecture was not built for realtime search applications. Realworld Results… After transitioning our search infrastructure from Solr to Elasticsearch, we saw an instant ~50x improvement in search performance! And now for something a bit more interesting… The typical realtime search architecture goes something like this: Elasticsearch can support this model quite well, but it also offers a feature that turns this entire workflow on it’s head.
Quick 'n' Comfortable Web Development in PHP | Nette Framework MySQL: Błąd „#1005 – Can’t create table (errno: 121)” podczas tworzenia kluczy obcych. Powoli wyjaśnia się moja sytuacja na uczelni, także mam czas na opisywanie bardziej ambitnych problemów. Dzisiejszy wpis sponsoruje przedmiot Hurtownie i Eksploracja Danych, w ramach którego w tym semestrze naszym zadaniem było m. in. zaprojektowanie rzeczonej hurtowni. Ze względu na to, że uwielbiam przedmioty pozwalające wykorzystać posiadaną wiedzę w praktyce, z przyjemnością zająłem się wykonaniem projektu. ;] Strukturę bazy danych obsługującej hurtownię projektowałem w narzędziu MySQL WorkBench, które z tego miejsca szczerze polecam – jak na darmowe oprogramowanie jest naprawdę bardzo solidnym produktem. Po wykonaniu części opisowej przypomniałem sobie, że trzeba jeszcze wstawić kod tworzący całą strukturę [zestaw zapytań CREATE TABLE wraz z odpowiednimi ALTER TABLE dla relacji]. Przywołałem okno Firefoksa, spojrzałem na strukturę bazy i nieco zdziwiony zobaczyłem tylko kilka tabel „liści”, nie posiadających żadnych kluczy obcych. #1005 – Can’t create table ‚. Gdzie jest błąd?
