When defining a mixed index, a list of parameters can be optionally JanusGraph with TinkerPop’s Hadoop-Gremlin tHighlightSimplePost("") 7.Search Predicates and Mixed Index Data Typesĭatatype and Attribute Serializer Configuration Default highlighting tag used by Solr is, but we can change this by setting the pre and post tags: tHighlightSimplePre("") Please notice that the search keyword Appliances is tagged with. We'll get the highLightedText as “Home Appliances”. 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) Let's index some documents and define keywords to be highlighted: itemSearchService.index("hm0001", "Brand1 Washing Machine", "Home Appliances", 100f) 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. 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. 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 –. We can use wildcard characters * and ? in our query: tQuery("*rand?") 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)
