Though the two search engines mentioned above actually utilize the ontology in Semantic Web, they have not fully utilized the essential matter of ontology, that is, the relations between concepts. title:text Easy usage is important. But even cheep old standard hardware is enough for a search server for gigabytes or terabytes or millions of documents.

If you need you can scale up to Big Data and very large document sets with vast amounts of documents: The main open source components like Apache Lucene, Apache Solr and Elastic Search are scalable to a search cluster for very large amounts of data, much load and for high availability. The search text:thermocouple would find all pages with the term thermocouple in the body text, without listing pages where only an image, or an alternative text tag for that image uses the word ‘thermocouple’. The software architecture is platform independent (Java & Python) and modular (keep it simple) and interoperable. Colleagues are able to find new data immediately without (often forgotten) uploads to a data or document management system (DMS) or filling out a data registration form for each new or changed document or dataset in a data management system, data registry or digital asset management (DAM) system. An RDF description (such descriptions are often referred to as metadata, or "data about data") can include the authors of the resource, date of creation or updating, the organization of the pages on a site (the sitemap), information that describes content in terms of audience or content rating, key words for search engine data collection, subject categories, and so forth. Example: To find recipes for cookies with oatmeal but without raisins, try "recipe cookie +oatmeal -raisin". That said, the common way is either to do OBDA or you convert the relational data to RDF triples. Included/Excluded The rules that are extricated are used to improve the performance of the meta-data based search engine. With its responsive design and open standards like HTML5 it is possible to search with tablets, smartphones and other mobiles.

Use url:products to find all pages on all servers that have the word ‘products’ in the host name, path, or filename - the complete URL, in other words. Search Engine Based on RDF Technology A method has been proposed in this paper to create an adaptive search engine which uses mining association rules that reflect the users past search history [10]. Example 1: To find references to spring loaded probe assemblies, type "spring loaded probe assemblies" in the search box. No matter if structured data like databases, tables or spreadsheets or unstructured data like text documents, E-Mails or even scanned legacy documents: Search in many different formats and content types (text files, Word and other Microsoft Office documents or OpenOffice documents, Excel or LibreOffice Calc tables, PDF, E-Mail, CSV, doc, images, photos, pictures, JPG, TIFF, videos and many other file formats). To make sure that a specific word is always included in your search topic, place the plus (+) symbol before the key word in the search box. So, when you perform a full-text search for “Bob”, you get a reference on all the resources that have “Bob” in one of the literals that describe these resources. Existing search facilities in this environment only support exact queries. Yet there is one semantic web tool which has grown in use and implementation—the Resource Description Framework (RDF). Download SPARQL Engine for free. Wild Cards Like we use standard open source software components, you can use and integrate our search engine components and research tools with your existing standard software environment and customize many options of powerful standard tools and frameworks. The Resource Description Framework provides a structured means of publishing information describing entities through use of RDF terms and RDF triples, and constitutes the core data model for our search engine. Following the linked data approach that all items should be identified using URI references, the search engine would crawl the Semantic Web, following resource URIs and indexing the found resources [2] . Working with open standards for Semantic Web and Linked Data like HTTP, HTML, CSS, RSS, RDF, SKOS, Dublin Core and a REST-API makes the open search platform flexible, extendable and interoperable with standard software and open for own developments. Here's how it works: you tell the search service what you're looking for by typing in keywords, phrases, or questions in the search box.

Working with open standards for Semantic Web and Linked Data like HTTP, HTML, CSS, RSS, RDF, SKOS, Dublin Core and a REST-API makes the open search platform flexible, extendable and interoperable with standard software and open for own developments..
