1. A method for providing recommendations to improve a query, comprising: receiving, from a user via a user interface, a query with query keywords and selected categories;calculating a query relevance indicator for each of the selected categories, wherein the query relevance indicator for a category of the selected categories is calculated based on a keyword relevance indicator of each keyword specified in the query, a total number of keywords in the query, a keyword relevance indicator of each keyword in the category that is not specified in the query, and a total number of different keywords in the category and the query; andin response to determining that the selected categories are ranked high with reference to the query relevance indicator for each of the selected categories, calculating a query relevance indicator for each subcategory, wherein the query relevance indicator for a subcategory is calculated based on the keyword relevance indicator of each keyword specified in the query, the total number of keywords in the query, a keyword relevance indicator of each keyword in the subcategory that is not specified in the query, and a total number of different keywords in the subcategory and the query;ranking each subcategory based on the query relevance indicator of the query with each subcategory; andin response to determining that high-ranked subcategories are not in the selected categories, providing recommendations of one or more new query keywords and the ranked subcategories for use in selecting new categories to be submitted with the query; andin response to receiving a new query using at least one of the one or more new query keywords, executing the new query to identify services. 2. The method of claim 1, further comprising: in response to determining that at least one of the selected categories is ranked low with reference to the query relevance indicator for each of the selected categories, identifying a pair of synonyms with a first one of the synonyms associated with a query keyword and a second one of the synonyms associated with a category keyword; andproviding a recommendation that the query keyword be replaced with a synonym from the pair of synonyms. 3. The method of claim 2, wherein the pair of synonyms is identified for the query keywords that have low keyword relevance indicators for non-top-ranked selected categories. 4. The method of claim 1, further comprising: for category keywords in non-top-ranked selected categories with high keyword relevance indicators, identifying the category keywords that are not in the query and for which synonyms are not identified; andproviding a recommendation that the identified category keywords be added to the query. 5. The method of claim 1, further comprising: identifying query keywords having low keyword relevance indicators for non-top-ranked selected categories and having high keyword relevance indicators for top-ranked, but un-selected categories;from the identified query keywords, identifying the query keywords for which synonyms are not identified; andproviding a recommendation that the query keywords for which synonyms were not identified be removed from the query. 6. The method of claim 1, further comprising: executing the query in a current form; andproviding a list of one or more services. 7. A system for providing recommendations to improve a query, comprising: a processor; anda matching engine coupled to the processor and performing operations, the operations comprising: receiving, from a user via a user interface, a query with query keywords and selected categories;calculating a query relevance indicator for each of the selected categories, wherein the query relevance indicator for a category of the selected categories is calculated based on a keyword relevance indicator of each keyword specified in the query, a total number of keywords in the query, a keyword relevance indicator of each keyword in the category that is not specified in the query, and a total number of different keywords in the category and the query; andin response to determining that the selected categories are ranked high with reference to the query relevance indicator for each of the selected categories, calculating a query relevance indicator for each subcategory, wherein the query relevance indicator for a subcategory is calculated based on the keyword relevance indicator of each keyword specified in the query, the total number of keywords in the query, a keyword relevance indicator of each keyword in the subcategory that is not specified in the query, and a total number of different keywords in the subcategory and the query;ranking each subcategory based on the query relevance indicator of the query with each subcategory; andin response to determining that high-ranked subcategories are not in the selected categories, providing recommendations of one or more new query keywords and the ranked subcategories for use in selecting new categories to be submitted with the query; andin response to receiving a new query using at least one of the one or more new query keywords, executing the new query to identify services. 8. The system of claim 7, wherein the operations further comprise: in response to determining that at least one of the selected categories is ranked low with reference to the query relevance indicator for each of the selected categories, identifying a pair of synonyms with a first one of the synonyms associated with a query keyword and a second one of the synonyms associated with a category keyword; andproviding a recommendation that the query keyword be replaced with a synonym from the pair of synonyms. 9. The system of claim 8, wherein the pair of synonyms is identified for the query keywords that have low keyword relevance indicators for non-top-ranked selected categories. 10. The system of claim 7, wherein the operations further comprise: for category keywords in non-top-ranked selected categories with high keyword relevance indicators, identifying the category keywords that are not in the query and for which synonyms are not identified; andproviding a recommendation that the identified category keywords be added to the query. 11. The system of claim 7, wherein the operations further comprise: identifying query keywords having low keyword relevance indicators for non-top-ranked selected categories and having high keyword relevance indicators for top-ranked, but un-selected categories;from the identified query keywords, identifying the query keywords for which synonyms are not identified; andproviding a recommendation that the query keywords for which synonyms were not identified be removed from the query. 12. The system of claim 7, wherein the operations further comprise: executing the query in a current form; andproviding a list of one or more services. 13. A computer program product for providing recommendations to improve a query, the computer program product comprising: a non-transitory computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising:computer readable program code, when executed by a processor of a computer, configured to perform:receiving, from a user via a user interface, a query with query keywords and selected categories;calculating a query relevance indicator for each of the selected categories, wherein the query relevance indicator for a category of the selected categories is calculated based on a keyword relevance indicator of each keyword specified in the query, a total number of keywords in the query, a keyword relevance indicator of each keyword in the category that is not specified in the query, and a total number of different keywords in the category and the query; andin response to determining that the selected categories are ranked high with reference to the query relevance indicator for each of the selected categories, calculating a query relevance indicator for each subcategory, wherein the query relevance indicator for a subcategory is calculated based on the keyword relevance indicator of each keyword specified in the query, the total number of keywords in the query, a keyword relevance indicator of each keyword in the subcategory that is not specified in the query, and a total number of different keywords in the subcategory and the query;ranking each subcategory based on the query relevance indicator of the query with each subcategory; andin response to determining that high-ranked subcategories are not in the selected categories, providing recommendations of one or more new query keywords and the ranked subcategories for use in selecting new categories to be submitted with the query; andin response to receiving a new query using at least one of the one or more new query keywords, executing the new query to identify services. 14.
