String highLightedText = highlightedList.get(0) List highlightedList = highlightedFieldMap.get("category") Map> highlightedFieldMap = hitHighlightedMap.get("hm0001") Map> hitHighlightedMap = response.getHighlighting() ItemSearchService.index("hm0004", "Brand2 Dishwasher", "Washing equipments", 250f) ItemSearchService.index("hm0003", "Brand2 Ceiling Fan", "Home Appliances", 200f) ItemSearchService.index("hm0002", "Brand1 Refrigerator", "Home Appliances", 300f) Their website is meant for the exchange of experiences among. At Greenice, we dealt with Solr while working on a project for an Australian client. Let's index some documents and define keywords to be highlighted: itemSearchService.index("hm0001", "Brand1 Washing Machine", "Home Appliances", 100f) Solr supports various suggester implementations, highlighting functionality (a visual indication of the words entered in the field) and spell checkers / Did you mean (which are absent in ES). This will be very helpful to get a better picture of the results. We may want the keywords in our search query to be highlighted in the results. ![]() Until you do this step, no suggestions are returned and you’ll see messages and/or stack traces in the logs. Build the suggester (Set the storeDir or indexPath parameter if desired). What's more, if we want to search on specific fields instead of all indexed fields, we can specify these in the query: tQuery("description:Brand* AND category:*Washing*") 4.2. You can issue these commands from a browser, curl, SolrJ etc. ![]() When you're done, you should at least have the bin and conf folder. You'll also need to copy the contents of the apache-solr-1.4.1\example\solr folder to your newly created Solr folder. Solr queries also support boolean operators like in SQL: tQuery("brand1 AND (Washing OR Refrigerator)") Īll boolean operators must be in all caps those backed by the query parser are AND, OR, NOT, and –. Now, we also need to create the Solr folder, which will host our Solr configuration files, indexes and so on. Some Examples From FuzzyLookupFactory: suggest. Here are some examples from a Wikipedia dump, the title field with the fieldType below. Simply issue /suggesthandlersuggest.qwhatever. We can use wildcard characters * and ? in our query: tQuery("*rand?") As you can see above, the suggester component is just a searchComponent, and we define it in a request handler. We want to search any word containing “rand”, that starts with any number of characters and ends with only one character. Note that simple searches are not case sensitive. The search query above will look for any documents that contain the complete word “brand1” in any of its indexed fields. The number of returned records will be 10, indexed from zero when start and rows are not specified. SolrJ will internally use the main query parameter q in its request to the server. List items = response.getBeans(Item.class) QueryResponse response = solrClient.query(query)
