    > How to Search in NewsIsFree

    Automated AND requests

    Search results include only the pages which display ALL searched words. There is no need to write "and" between words. In order to narrow and specify the search, just enter few more words.

    For instance,

    will find all the responses in which the words bush and george have occurred.

    For instance, will find all the responses in which words bush and george have occurred, and which concern iraq.

    Entry of multilingual data

    You can enter a search text in several languages or character sets and receive the corresponding results in all the languages at once (The system uses UTF-8 as the common codebase). For instance:

    Selection of keywords

    In order to receive better results, it is important to select keywords. Follow these tips:

    • At first, try to enter obvious words. If you are looking for information about "heineken", enter "heineken", but not "dutch beer".
    • Enter as many specific keywords as possible. For instance, "tom hanks" will give more significant results than "actor in the movies philadelphia, ladykillers and terminal".

    Ignored words

    Our search does not take into consideration frequently used words and symbols, or the so-called ignored words. Our search always ignores, for instance, the marks "http" and ".com", as well as some numbers and letters, if they do not help in the search process and/or seriously delay it.

    For instance, will ignore the word and, and will perform the search as if only the word lucene and the word rating were entered.

    Nevertheless, in order to include ignored words into the search, use "+" sign. Always leave a space before "+" sign. You can insert "+" sign when you are looking for a phrase.

    For instance, will find only the responses concerning Lursoft databases, which are situated on the Internet domain LV.

    Displaying of found search context

    In order to see the found words in the page context, one or few extracts from the content of every found Web-page will be displayed.

    Phrase search

    You can search for precise phrases containing one or a few side-words. In this case just write a text containing search phrases enclosed in quotation marks.

    For instance, will find all responses concerning the popular Valentine Day, but not the responses in which the word Valentine and the word Day occur separately.

    When searching for a phrase, take into consideration that only pages containing the precise word combination of the search phrase will be found, and with just the specific word sequence.

    Phrase can contain several words, for instance, will find the responses containing this phrase in the text content.

    Word exclusion by use of "-" sign

    You have the possibility to narrow search even more by entrusting our Search Engine to exclude separate words or phrases from the list of results. For this purpose use 'minus' sign "-" adding it before word or phrase to be excluded. The 'minus' sign must be always preceded by one space.

    For instance, will find the responses concerning windows only, but not the popular Microsoft Windows operating system.

    Similar results will be obtained with: ; it differs from the previous result by the fact that only responses containing the exact phrase "Microsoft Windows" will be excluded.

    Search with OR

    Our search system supports the search by one or a few indicated words, processing the search request using OR logic. In this case you have to indicate alternative words in figure brackets {}.

    For instance, will find all responses in which the word public, the word holidays and at least one of the two OR-words - Christmas or Easter occur.

    Combination of logical conditions by use of brackets ()

    Our search system supports the search combining one or a few logical conditions using brackets. By these means it is possible to combine several logical AND and OR searching constraints.

    For instance, will find all responses in which the word public and the word days occur together or at least one of the two indicated OR words- Christmas or Easter occurs.

    Word cases and variations

    In order to obtain the most precise search results, our system can search for word case variations and substitute words.

    This is a special function of our Search Engine. The function provides the search of the Internet content directly in various national languages in cases when word endings are changeable.

    You can select this mode, if the tick mark: [ in word forms ] is visible in the search field.

    Word synonyms

    We provide you the possibility to search not only for the words you have entered, but also for synonyms of the words using a dictionary, which can add one or several synonyms in the same language to every search word.

    You can select this mode, if the tick mark: [ synonyms ]. is visible in the search field.

    Template search using part of a word

    In order to mark a part of a search word or a phrase, you can use asterisk sign '*' as a template for our search system.

    For instance, will find all responses containing the word English and either the word dictionary or dictionaries.

    If you enter a template which has too many matches, our search system can limit the quantity of returned results. In this case you'll see a warning at the beginning of the list o fresults.Avoidtheuseof unspecific word templates, such as man*, new*, with*, for*, etc.

    During template search, our Search Engine will first of all select word forms which are the closest to the template. Therefore, in cases when the quantity of returned results is limited during template search, the result will include template-closest rather than the rarely occurring words.

    For instance, entering , as the result you will receive the words baby or babies, but not the words baby-sitter, babyhood or baby-farmer and other variations. In order to find longer words using template search, always enter the longest unchangeable part of the template word; it will you give you the most significant and precise results.

    For instance, if you enter , our search engine will find responses concerning only babysitter, but not any other babies-related issues.

    ATTENTION! When you are using asterisk sign '*' as a part of word template, make sure that the entered word contains at least 3 other letters or symbols. This restriction is necessary so as not to search for a vast volume of word variations, and in order to provide required minimum search speed of the our search system.

    Word letters variation search

    In order to mark an unknown letter of a searched word, you can use question mark '?' as a template for our search engine.

    For instance, will find all responses containing the word ship and all possible variations of the second word, such as Nahimov and Nakimov.

    Also, if you enter , our search engine will find both running and ringing.

    ATTENTION! Using question mark '?' as a letter template, the entered word must contain no more than 3 of them. This restriction is necessary so as not to search for a vast volume of word variations, and in order to provide required minimum search speed of our search engine.

    Are the capital letters important?

    The NewsIsFree Search Engine does not take capital letters into account. All entered letters are considered as lower case.

    For instance, if you are searching either for or
    or or , the results will always be the same.

    Still, you have the possibility to search for proper nouns, or the words which are usually written beginning with a capital letter, using "Advanced search" mode. However, these results will not always be completely precise, since Lucene will also find the words from the beginnings of the sentences. A sentence containing textual data almost in all cases has a capital letter at the beginning.

    You can select this mode, if the tick mark: [ Exact Match ] is visible in the Advanced search field, or in additional options.

    The NewsIsFree Search Engine takes into account accents and diacritical signs. If you wish so that specific characters of national languages would not be taken into account, and would be automatically transliterated into "hard" letters, you can use "Advanced search" mode.

    Advanced search

    The NewsIsFree Search Engine enables you to perform advanced search with additional selection criteria. In order to get access to the additional options, you have to select "Advanced search" link.

    We provide you the possibility for extra filtration of information of the found web-pages by languages, names of the source, categories as well as date and popularity filters.

    Using "Advanced search" it is possible to set up the more precise search conditions, including the search for special words in special data arrays only, or to choose ordering of the results. Using "Advanced search" mode it is possible to set up the number of search results displayed on one screen page, different from the original value 10 (it can be increased up to 100).
