Meanwhile, the budding research scholars are still wondering if it is a reliable academic search engine or if they should rely on other exhaustive search engines like Web of Science, Scopus, and SciSpace. Consequently, some users request feature updates with advanced search options or services, while others dig into the sources' credibility. As a result, many users started questioning the reliability of the platform. Over the years, with the advent of gaming, inaccurate citation counts, no periodic data updates, and other platform-centric concerns ascended gradually. The launch of Google Scholar in November 2004 took the scholarly communication world by storm by authenticating the true meaning of Google, i.e., "largest information resource."Īt first, researchers worldwide acknowledged this new product of Google intended to empower research by transforming the research-finding process. : : PKIX path validation failed: : signature check failedĪt .getSSLException(Unknown Source) ~Īt .fatal(Unknown Source) ~Īt .fatalSE(Unknown Source) ~Īt .serverCertificate(Unknown Source) ~Īt .processMessage(Unknown Source) ~Īt .processLoop(Unknown Source) ~Īt .process_record(Unknown Source) ~Īt .readRecord(Unknown Source) ~Īt .performInitialHandshake(Unknown Source) ~Īt .startHandshake(Unknown Source) ~Īt net.sf.getLatestVersion(Version.java:58) ~Īt net.sf.doInBackground(VersionWorker.java:37) Īt net.sf.doInBackground(VersionWorker.java:18) Īt $1.call(Unknown Source) Īt .run(Unknown Source) Īt (Unknown Source) Īt .runWorker(Unknown Source) Īt $n(Unknown Source) Īt (Unknown Source) Ĭaused by: : PKIX path validation failed: : signature check failedĪt .doValidate(Unknown Source) ~Īt .engineValidate(Unknown Source) ~Īt .validate(Unknown Source) ~Īt 509TrustManagerImpl.validate(Unknown Source) ~Īt 509TrustManagerImpl.checkTrusted(Unknown Source) ~Īt 509TrustManagerImpl.checkServerTrusted(Unknown Source) ~Ĭaused by: : signature check failedĪt .PKIXMasterCertPathValidator.validate(Unknown Source) ~Īt .PKIXCertPathValidator.validate(Unknown Source) ~Īt .PKIXCertPathValidator.engineValidate(Unknown Source) ~Īt .validate(Unknown Source) ~Ĭaused by: : Signature does not match.Īt 509CertImpl.verify(Unknown Source) ~Īt .BasicChecker.verifySignature(Unknown Source) ~Īt .BasicChecker.check(Unknown Source) ~Ġ9:57:31.696 WARN net.sf. - Could not copy inputĪt net.sf.openConnection(URLDownload.java:110) ~Īt net.sf.downloadToString(URLDownload.java:123) ~Īt net.sf.nConfig(GoogleScholarFetcher.java:156) ~Īt net.sf.GoogleScholarFetcher.processQueryGetPreview(GoogleScholarFetcher.java:82) ~Īt net.sf.GeneralFetcher.lambda$actionPerformed$4(GeneralFetcher.java:191) ~Īt 509TrustManagerImpl.When Google was officially launched as a web-based search engine, none of us would have thought it could address academicians' research discovery problems via "Google Scholar." This is what I’m getting in the error console log:Ġ9:56:35.565 INFO net.sf. - Opening: C:\xampp\htdocs\Project\Research\Bibliography.bibĠ9:56:48.079 WARN net.sf. - Could not connect to the updateserver. I can use Google Scholar in my browser too. However, yesterday and today, after I click to search for an item, I get an alert box saying “Error while fetching from Google Scholar”. Up until yesterday, I was able to search using Google Scholar.
