![]() 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) To demonstrate the filter query usage, we will create a core in Solr using basic configuration and index a sample file shipped along with Solr installation. 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. Lets begin by learning how Solrs spell-check. ![]() We may want the keywords in our search query to be highlighted in the results. Autosuggest gives immediate feedback to users by showing valid query terms available in the index as they type. Solr updates the cores or indexes and returns the result of the query in XML or JSON format. 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. Filtering queries are simple checks for set inclusion/exclusion, which make them very fast to compute. It also describes how to define your own custom filters. 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) P.S - The context filter query described in only works with a single indexed field, so this will not work with my use case.QueryResponse response = solrClient.query(query) I defined my Suggest Component along with the Request Handler with the following: My question is: can i create a new similar plugin, as described above, that works with the Suggest Component? Because when I index a document, the user may have (or not) permissions to see that document, so the suggester shouldn’t show suggestions that the user hasn’t permissions to see. Note that the code above works well with the Search Component with an edismax type. To call this plugin, i only have to set the fq parameter with the along with the other query parameters. ![]() ![]() To achieve that i created a Query Parser (called DocumentsByUserParser that extends the class QParserPlugin) defined in the solrconfig.xml with the following: I created a plugin for Solr (version 6.3) that adds a permission layer to filter the retrieved documents using a database query (e.g: the user with ID 2 hasn’t permissions to see the document with the ID 1) As the logic that defines if a user has permissions needs fields that aren’t indexed in the Solr, I need to check in the database. ![]()
